Pelvic Pain and Acupuncture: A Traditional Chinese Medicine Approach

By Dr (TCM) Attilio D'Alberto | Traditional Chinese Medicine Practitioner, Wokingham

Pelvic pain is one of the most debilitating and frequently misunderstood symptoms in women's health. It may be cyclical — arriving with menstruation, ovulation or specific phases of the cycle — or constant, affecting daily activity, sleep and quality of life regardless of where a woman is in her cycle. It may be associated with a diagnosed condition such as endometriosis or polycystic ovary syndrome (PCOS), or it may be classified as chronic pelvic pain (CPP) in the absence of identifiable pathology. In pregnancy, pelvic girdle pain (PGP) affects a significant proportion of women and can make even basic movement extremely difficult. What all of these presentations share is that conventional medicine frequently underserves them — offering only symptom suppression with painkillers, hormonal contraception or surgery, without addressing the underlying imbalance driving the pain. Acupuncture and traditional Chinese medicine (TCM) offer a different framework: one that focuses on restoring the free flow of Qi and Blood through the pelvis, resolving pathogenic factors such as Cold, Dampness and Blood stasis, and addressing the neuroendocrine dysregulation that underlies many types of pelvic pain.

1. Types of pelvic pain and their causes

Pelvic pain covers a wide spectrum of presentations. Understanding which type a person is experiencing — and what is driving it — is essential for effective treatment.

Dysmenorrhoea (painful periods): Primary dysmenorrhoea refers to painful periods without identified pathology. It is caused by excessive prostaglandin production in the uterine lining, triggering strong uterine contractions that temporarily restrict blood supply, producing ischaemic (cramp-like) pain. Secondary dysmenorrhoea refers to painful periods caused by an underlying condition — most commonly endometriosis, adenomyosis or fibroids.

Endometriosis: Endometrial-like tissue implants outside the uterus, most commonly on the ovaries, fallopian tubes, bladder, bowel and pelvic peritoneum. These implants respond to the menstrual cycle, bleeding and causing inflammation, scarring and adhesions. Pain is typically cyclical but can become constant in advanced stages.

Adenomyosis: Endometrial tissue invades the muscular wall of the uterus (myometrium), causing the uterus to become enlarged, tender and dysfunctional. It typically causes heavy, painful periods and a diffuse, aching pelvic pain.

PCOS and ovarian pain: Women with PCOS may experience mid-cycle pelvic pain, heaviness and discomfort related to the multiple cysts on the ovaries and hormonal dysregulation.

Interstitial cystitis / bladder pain syndrome: Chronic bladder pain and urgency without infection, often co-occurring with other pelvic pain conditions.

Pelvic inflammatory disease (PID): Infection of the reproductive organs, often bacterial in origin, causing acute or chronic pelvic pain with associated discharge and systemic symptoms.

Chronic pelvic pain (CPP): Defined as pelvic pain lasting six months or more that is not exclusively related to menstruation or intercourse and is not caused by an identified pathology. CPP involves central sensitisation — the nervous system becomes chronically activated — making the pain self-perpetuating even after the initial trigger has resolved.

Pregnancy-related pelvic girdle pain (PGP) / symphysis pubis dysfunction (SPD): Instability and pain in the pelvic joints during pregnancy, driven by hormonal changes (primarily relaxin) that loosen the pelvic ligaments beyond optimal function.

2. Endometriosis and adenomyosis

Endometriosis affects approximately 1 in 10 women of reproductive age. It takes an average of 7–10 years from symptom onset to diagnosis, largely because its symptoms — painful periods, deep dyspareunia (pain during sex), bowel and bladder changes with menstruation, fatigue — are frequently normalised or attributed to other causes. This diagnostic delay is not trivial: endometriosis is progressive, and the longer it remains untreated, the more adhesions and scarring develop, with implications for both pain and fertility.

Conventional management includes hormonal suppression (combined pill, GnRH analogues, Mirena coil), NSAID pain management and laparoscopic excision surgery. None of these address the underlying inflammatory and immune dysregulation that is increasingly understood to drive endometriosis. Surgical excision has the best long-term outcomes when performed thoroughly, but recurrence rates remain significant, and many women find that their pain returns within a few years of surgery.

Adenomyosis was historically difficult to diagnose without hysterectomy but can now be identified on MRI and, increasingly, by experienced practitioners using transvaginal ultrasound. It affects women in their thirties and forties predominantly, and may coexist with endometriosis. Conventional options are limited to hormonal suppression or hysterectomy for severe cases; this is a condition where integrative approaches are particularly valued.

Both conditions have a clear TCM pathology (see section 6) and respond well to acupuncture and herbal medicine, particularly for pain management, reduction of inflammation, and support of fertility where conception is the goal.

3. PCOS and ovarian pain

Polycystic ovary syndrome is primarily a hormonal and metabolic condition, but pelvic discomfort is common — particularly mid-cycle, where the enlarged ovaries and multiple developing follicles create a sense of heaviness, pressure or aching. Ovulation-related pain (mittelschmerz) may be more pronounced in women with PCOS, and the failure of dominant follicle development (anovulation) can result in a cycle of follicular growth and atresia without the resolution of successful ovulation.

PCOS pelvic pain is driven by the hormonal imbalance — elevated LH, insulin resistance and androgen excess — and by the chronic low-grade inflammation that characterises the condition. Acupuncture addresses all three of these mechanisms, as detailed in section 7.

Further detail on the TCM and acupuncture approach to PCOS specifically is covered in the PCOS page.

4. Chronic pelvic pain (CPP)

CPP is among the most challenging presentations in women's health precisely because its mechanisms extend beyond the pelvis. When pain persists for six months or more, neuroplastic changes occur in the spinal cord and brain that make the pain self-sustaining. The dorsal horn of the spinal cord becomes sensitised, lowering the threshold at which signals are interpreted as painful. The anterior cingulate cortex and insula — regions involved in the affective component of pain — show altered activation patterns. The result is a condition that cannot be adequately treated by treating only the pelvis.

This is where acupuncture has a significant advantage. Acupuncture works on multiple levels simultaneously: it modulates descending pain inhibitory systems (releasing endorphins, enkephalins and dynorphins); it reduces spinal cord sensitisation via segmental inhibition; it regulates hypothalamic-pituitary-adrenal (HPA) axis function, which is frequently dysregulated in chronic pain states; and it activates the parasympathetic nervous system, shifting the autonomic balance away from the chronic sympathetic activation that maintains sensitisation. This multi-level action means that acupuncture addresses both the peripheral and central components of CPP in ways that isolated pharmaceutical interventions cannot.

CPP is frequently associated with a history of trauma, emotional suppression, or chronic stress — all of which are recognised in TCM as causes of Liver Qi stagnation, which is the most common TCM pattern in CPP (see section 6).

5. Pregnancy-related pelvic girdle pain (PGP)

Pelvic girdle pain during pregnancy is far more common than is often appreciated. As noted in My Pregnancy Guide, pregnancy-related PGP (also referred to as symphysis pubis dysfunction, or SPD) affects one in three pregnant women. It ranges from mild discomfort that responds to simple postural adjustments to severe, disabling pain that restricts walking, climbing stairs and turning in bed.

PGP is caused by the ligamentous laxity induced by relaxin (the hormone that loosens pelvic ligaments to prepare for birth), which, in some women, creates instability and asymmetry in the sacroiliac joints and pubic symphysis. Risk factors include a history of pelvic pain before pregnancy, previous PGP in a prior pregnancy, high BMI, and hypermobility. It tends to worsen progressively through pregnancy and can persist postnatally.

Standard management involves physiotherapy, pelvic girdle belts, activity modification and crutches in severe cases. Pain management options in pregnancy are limited by safety concerns. As noted in My Pregnancy Guide, research has shown that acupuncture can help reduce PGP and is safe to use in pregnancy. A randomised controlled trial published in Acta Obstetricia et Gynecologica Scandinavica found that acupuncture was superior to both physiotherapy and a control intervention for pregnancy-related PGP, with significant reductions in pain and disability scores. Acupuncture achieves this through a combination of mechanisms: reducing the inflammatory mediators at the joint surfaces, stimulating the release of endogenous opioids, relaxing the surrounding musculature, and modulating the central pain processing that amplifies PGP in some women.

Treatment typically involves weekly sessions from the point of onset, with points selected on the lower back, sacrum, hips and legs. Electro-acupuncture (where a gentle electrical current is passed between needles) is often used for its enhanced analgesic effect in musculoskeletal presentations. Needling in pregnancy is adapted to avoid contraindicated points and is entirely safe when performed by a practitioner experienced in obstetric acupuncture.

6. TCM patterns underlying pelvic pain

In traditional Chinese medicine, pain results from obstruction — anything that prevents the free flow of Qi (vital energy) and Blood through the channels and organs produces pain. The precise character of the pain, its timing within the cycle, the factors that aggravate or relieve it, and its accompanying symptoms all point to specific TCM patterns requiring specific treatments. The most common TCM patterns in pelvic pain are as follows.

Blood stasis

Blood stasis is the most common single pattern in severe, endometriosis-type dysmenorrhoea and adenomyosis. It is characterised by fixed, stabbing or boring pain that is worse with pressure, dark or clotted menstrual blood, and pain that is often worst at the start of the period when the uterus begins to contract and expel. The tongue typically has a purple tinge or purple spots on its sides, and the pulse is wiry or choppy. Blood stasis can arise from cold invasion (Cold stagnates Blood), Qi stagnation (Qi moves Blood; if Qi stagnates, Blood follows), trauma, or constitutional tendency. Treatment focuses on invigorating Blood and resolving stasis.

Liver Qi stagnation

The Liver governs the smooth flow of Qi through the body and has a particular relationship with the reproductive system through its internal channel pathway. Emotional suppression, stress, frustration and unexpressed anger all constrain Liver Qi, creating the stagnation pattern. This presents as premenstrual breast distension, mood changes, irritability, bloating and pelvic heaviness or aching that is worse with emotional stress and better with movement. The pain is typically dull-to-aching rather than sharp. Liver Qi stagnation frequently precedes or coexists with Blood stasis. Treatment focuses on coursing Liver Qi and resolving constraint.

Cold in the uterus (Cold Bi)

Uterine Cold is a common pattern in women who have chronic exposure to cold (cold environment, cold foods, swimming in cold water) or whose constitution tends to cold. The cold constricts the uterine vessels, causing severe cramping pain that is relieved by heat, pale or scanty menstrual blood, coldness of the lower abdomen, and often nausea and loose stools with menstruation. Moxa (moxibustion — the burning of dried mugwort herb over acupuncture points) is particularly effective for this pattern, warming the channels and uterus directly.

Damp-Heat

Damp-heat in the lower jiao (lower body cavity) typically presents as burning or heavy pelvic pain, often worse in hot or humid weather, associated with yellow or offensive vaginal discharge, painful urination, and a heavy, uncomfortable sensation rather than the cramping quality of Cold patterns. The tongue is red with a yellow greasy coating. Damp-heat arises from dietary excess (alcohol, sugar, greasy foods), chronic infection or constitutional predisposition, and requires a different treatment strategy — one that clears heat and resolves dampness rather than warming.

Kidney and Liver deficiency

A deficiency pattern presents differently from excess patterns: the pain is typically dull, aching, and relieved by rest and warmth. It may occur throughout the cycle rather than only perimenstrually, and is accompanied by signs of Kidney deficiency (lower back ache, fatigue, urinary frequency, tinnitus) and/or Liver Blood deficiency (scanty or pale periods, dizziness, visual disturbance, dry hair and skin). This pattern is more common in older women, those who are constitutionally weak, or after significant blood loss. Treatment involves nourishing the Kidney and Liver rather than aggressively moving Qi and Blood.

7. How acupuncture treats pelvic pain

Acupuncture's mechanisms in pelvic pain are among the best studied of all its applications. Its efficacy in dysmenorrhoea, endometriosis-related pain, and musculoskeletal pelvic pain is supported by a growing body of controlled clinical trials.

Endogenous opioid release: Acupuncture stimulates the release of beta-endorphins, encephalins and dynorphins from the brain, pituitary and spinal cord. These are the body's own pain-relieving substances, with analgesic potency comparable to pharmaceutical opioids but without dependency. This mechanism explains why acupuncture often produces a profound sense of relaxation alongside pain relief.

Prostaglandin regulation: Primary dysmenorrhoea is prostaglandin-mediated. Research has demonstrated that acupuncture reduces levels of PGF2α and PGE2 — the prostaglandins responsible for uterine cramping — and modulates the ratio of inflammatory to anti-inflammatory prostaglandins. This is a direct mechanism explaining why acupuncture reduces menstrual pain more effectively than merely distracting the nervous system.

Pelvic blood flow: Acupuncture at specific points — particularly SP6, ST36, CV4 and the sacral points — increases uterine and ovarian blood flow measurably on Doppler ultrasound. Improved pelvic circulation reduces ischaemia (blood supply restriction that causes cramping), promotes tissue healing in conditions like endometriosis, and improves the nutritive supply to the ovaries and endometrium.

Anti-inflammatory effects: Acupuncture activates the cholinergic anti-inflammatory pathway via the vagus nerve, reducing systemic and local inflammatory cytokine levels (IL-1β, TNF-α, IL-6). In endometriosis, which is fundamentally an inflammatory condition, this has clinically meaningful effects on lesion activity and pain intensity.

Central sensitisation and pain processing: Functional MRI studies demonstrate that acupuncture modulates activity in pain-processing brain regions including the anterior cingulate cortex, insula and periaqueductal grey matter. For CPP, where central sensitisation has become a self-sustaining driver of pain, this central modulation is a crucial mechanism — one that conventional analgesics address only partially.

HPA axis regulation: Chronic pelvic pain is associated with HPA dysregulation — elevated cortisol, altered cortisol awakening response, and impaired negative feedback. Acupuncture normalises HPA axis function, which reduces the amplification of pain signalling that chronic stress produces.

Treatment frequency depends on severity and chronicity. Acute dysmenorrhoea typically responds within three to four cycles of treatment, with sessions scheduled around the painful phase of the cycle. Chronic conditions including endometriosis, adenomyosis and CPP typically require weekly sessions for eight to twelve weeks before the full benefit is established, followed by monthly maintenance to prevent recurrence.

In pregnancy, acupuncture for PGP is typically delivered weekly from the onset of symptoms, using a modified point selection that avoids contraindicated combinations.

8. Chinese herbal medicine for pelvic pain

Chinese herbal medicine is a powerful complement to acupuncture for pelvic pain, particularly for Blood stasis conditions such as endometriosis and adenomyosis where the treatment objective is to break down existing stasis and prevent its re-accumulation.

Key formulas used in clinical practice include:

• Gui Zhi Fu Ling Wan: One of the most researched TCM formulas for endometriosis. Contains peach kernel (Tao Ren), red peony (Chi Shao), tree peony root bark (Mu Dan Pi), Poria (Fu Ling) and cinnamon twig (Gui Zhi). It invigorates Blood, resolves stasis and reduces pelvic masses. Clinical trials have shown it reduces dysmenorrhoea scores and CA-125 levels (a marker of endometrial activity) in endometriosis patients.
• Shao Fu Zhu Yu Tang: A warming formula for Cold-Blood stasis pattern, with particular application for severe lower abdominal cramping with cold signs. Contains fennel seed, ginger, cinnamon, corydalis (Yan Hu Suo) and other Blood-moving herbs.
• Long Dan Xie Gan Tang: For Damp-Heat patterns with burning pelvic pain, yellow discharge and signs of heat. Clears liver heat and resolves damp-heat from the lower jiao.
• Xiao Yao San: The classic formula for Liver Qi stagnation with Blood deficiency. Suitable for the aching, premenstrual pattern of pelvic discomfort associated with emotional stress. Contains bupleurum (Chai Hu), Chinese angelica (Dang Gui), white peony (Bai Shao), white atractylodes (Bai Zhu), Poria (Fu Ling) and licorice.

Formulas are always modified to the individual constitution and specific symptom picture — TCM herbal medicine is never applied as a one-size-fits-all intervention. Chinese herbs are generally not used in the first trimester of pregnancy; in the second and third trimester, specifically appropriate herbs can be used when indicated, with careful selection by a qualified practitioner.

9. Diet and lifestyle support

Dietary choices have a meaningful impact on pelvic pain, particularly where inflammation is a driver — as in endometriosis, adenomyosis and PCOS.

Anti-inflammatory diet: Omega-3 fatty acids (oily fish, flaxseed, walnuts) reduce the production of inflammatory prostaglandins. Studies in endometriosis patients show that higher omega-3 intake correlates with lower pain scores. Conversely, arachidonic acid (found in red meat and processed foods) is a precursor to the PGF2α and PGE2 that drive uterine cramping — reducing intake is a practical intervention for dysmenorrhoea.

Avoid cold foods and drinks from a TCM perspective: Particularly important for women with the Cold in the uterus pattern — cold foods (ice cream, cold smoothies, raw vegetables) and cold drinks constrict the uterine vessels and exacerbate cramping. Warming foods such as ginger, cinnamon, black pepper, root vegetables and soups support the uterine Yang.

Reduce phytooestrogens and xeno-oestrogens where oestrogen dominance is a driver: Endometriosis is an oestrogen-dependent condition. Minimising phytooestrogens (flaxseeds in excess, soy products), reducing exposure to xenoestrogens (BPA in plastics, pesticide residues) and supporting liver oestrogen clearance (cruciferous vegetables, DIM supplementation) can reduce oestrogenic stimulation of endometrial implants.

Supplements with evidence: Magnesium (300–400mg daily) reduces uterine muscle spasm and prostaglandin production — a well-supported intervention for primary dysmenorrhoea. Omega-3 (at least 2g daily EPA+DHA) reduces inflammatory prostaglandins. NAC (N-acetyl-cysteine) has specific evidence for endometriosis, with one controlled trial showing it reduced endometrioma size and pain scores. Vitamin D deficiency is associated with worse endometriosis pain scores and should be corrected.

Heat therapy: A heated pad or wheat bag on the lower abdomen provides significant relief for Cold and Blood stasis patterns, as heat promotes vasodilation and muscle relaxation. Moxibustion at home (using moxa sticks over CV4 and CV6) extends the warming treatment between clinic sessions.

Movement: Gentle movement — yoga, swimming, walking — improves pelvic blood flow and reduces prostaglandin sensitivity. High-intensity exercise during the painful phase of the cycle may aggravate symptoms; gentle, warm movement is preferred.

10. Pelvic pain and fertility

Pelvic pain and fertility are intimately connected. The most common causes of pelvic pain in reproductive-age women — endometriosis, adenomyosis, PCOS and CPP — all carry implications for conception, whether through distortion of pelvic anatomy, impairment of follicular development, disruption of implantation or the systemic inflammatory and hormonal dysregulation that reduces fertility potential.

Endometriosis is found in 25–50% of women presenting with infertility — a rate far above its prevalence in the general population. It impacts fertility through multiple mechanisms: ovarian endometriomas reduce ovarian reserve and egg quality; adhesions can block or distort the fallopian tubes; peritoneal fluid changes create a hostile environment for fertilisation and early embryo development; and the immune dysregulation associated with endometriosis may impair implantation. Women with endometriosis who are trying to conceive benefit significantly from a combined approach — managing the inflammatory and stasis component with acupuncture and herbs while preparing the body for conception, and working alongside the gynaecology team to determine whether surgical treatment of lesions is appropriate before an IVF cycle.

Adenomyosis has a demonstrated negative impact on IVF outcomes, with lower implantation and clinical pregnancy rates. Endometrial receptivity is specifically impaired, and uterine contractility is abnormal. Acupuncture in the weeks before an embryo transfer can reduce abnormal uterine contractions and improve endometrial blood flow — both of which are relevant in adenomyosis.

For women with pelvic pain who are trying to conceive naturally, the pain management itself benefits fertility: reducing prostaglandins reduces uterine spasm at the time of ovulation (which can impair egg release and transport), improving pelvic blood flow enhances follicular development and endometrial quality, and the stress reduction associated with acupuncture reduces cortisol's inhibitory effects on the reproductive hormonal axis. More detail on the fertility-specific aspects of acupuncture is available on the acupuncture for fertility page.
