What causes chronic pelvic pain?

Chronic pelvic pain is almost never caused by a single condition. In women, the most common contributors are endometriosis, adenomyosis, hypertonic pelvic floor muscles, irritable bowel syndrome, interstitial cystitis / bladder pain syndrome, and adhesions from past infections or surgery. In men, chronic prostatitis / chronic pelvic pain syndrome and hypertonic pelvic floor are the predominant drivers. Central sensitisation — where the nervous system becomes hypersensitive over time from repeated pain input — is present in most people with longstanding pelvic pain and explains why the pain can seem disproportionate to any identifiable structural cause. A history of physical or sexual trauma is found in around 30–50% of people with chronic pelvic pain.

Do I need a laparoscopy to diagnose endometriosis?

Not necessarily anymore. The European Society of Human Reproduction and Embryology (ESHRE) 2022 guideline and the Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) now both support a clinical and imaging diagnosis of endometriosis in appropriate patients, without requiring laparoscopy. Laparoscopy is reserved for situations where: hormonal treatment has failed at six months, fertility is being investigated, imaging suggests deep infiltrating disease, an endometrioma over 3 cm is present, or there is suspected bowel or bladder involvement. An empirical hormonal trial with a combined pill or progestin (such as dienogest) is reasonable first-line management while waiting for specialist review.

What is pelvic floor physiotherapy and how does it help?

In chronic pelvic pain, the pelvic floor muscles are usually hypertonic — chronically tense rather than weak. Pelvic floor physiotherapy for chronic pelvic pain focuses on relaxation and down-training, not strengthening. Kegel exercises, commonly recommended for bladder leakage, actively worsen hypertonic pelvic floor pain and should be avoided unless specifically advised by a physio who has assessed your pelvic floor. A trained women's health or men's health physiotherapist uses internal palpation, breathing techniques, and relaxation strategies to release muscle tension. This is funded under the GP Chronic Condition Management Plan for eligible patients.

Is pain medication helpful for chronic pelvic pain?

Simple analgesics — paracetamol and NSAIDs — help during flares but do not address the underlying drivers and are not appropriate as sole long-term management. Low-dose amitriptyline (10–25 mg at night) is the most evidence-supported systemic medication across the common chronic pelvic pain conditions, including interstitial cystitis, irritable bowel syndrome, vulvodynia, and chronic prostatitis. Hormonal suppression (combined pill, Mirena IUD, dienogest) is first-line in women with suspected endometriosis. The GaPP2 clinical trial showed gabapentin was not more effective than placebo for chronic pelvic pain in women — so it is not routinely recommended. Long-term opioids worsen chronic pelvic pain and cause significant harm, and should be avoided.

What should I expect at my first GP appointment for chronic pelvic pain?

A good first appointment for chronic pelvic pain covers a comprehensive history including bowel, bladder, menstrual, sexual, and psychological wellbeing — and often includes sensitive questions about past trauma, which is highly prevalent in this condition. A physical examination typically includes an abdominal assessment, pelvic floor muscle assessment, and pelvic examination in women. Blood tests, urine, and a pelvic ultrasound are usually ordered. Importantly, treatment should begin at the first visit — a referral for pelvic floor physiotherapy and a Mental Health Treatment Plan for psychology can both be initiated before a definitive diagnosis is established. You should not have to wait for a laparoscopy before receiving support.

Chronic pelvic pain

Chronic pelvic pain: multimodal care from day one

By Dr HB Lo, FACRRM Reviewed 5 July 2026 11 min read

Chronic pelvic pain — pain lasting six or more months severe enough to cause disability — affects 15–25% of women and 5–10% of men over their lifetime, with an average diagnostic delay of four to seven years.

The pathophysiology is almost always multifactorial: gynaecological, urological, gastrointestinal, musculoskeletal, and neurological drivers reinforce each other through central sensitisation. The most common contributors are hypertonic pelvic floor, endometriosis, irritable bowel syndrome, and interstitial cystitis.

Multimodal treatment — pelvic floor physiotherapy, pain education, and psychological therapy — should begin at the first visit, not after a definitive diagnosis.

What chronic pelvic pain actually is

Chronic pelvic pain (CPP) is pelvic pain lasting six or more months, severe enough to cause functional disability or prompt healthcare visits, that is not exclusively explained by a single identified condition. It affects roughly 15–25% of women and 5–10% of men over their lifetime, and the average delay from symptom onset to diagnosis is four to seven years — during which people are often dismissed, misattributed, or told nothing is wrong.

The condition costs Australia an estimated $9 billion per year in lost productivity and direct healthcare costs, driven largely by endometriosis alone, according to Endometriosis Australia. The Pelvic Pain Foundation Australia estimates that only 30% of those affected receive a diagnosis.

The single most important framing to hold: chronic pelvic pain is almost always multifactorial. The gynaecological, urological, gastrointestinal, musculoskeletal, and neurological drivers overlap, reinforce each other, and evolve over time. Treating one driver while ignoring others rarely produces sustained relief.

A. Core clinical — the AU general practice framework

Causes — the multifactorial map

Gynaecological (women):

Endometriosis / adenomyosis — cyclical or acyclical; associated with painful intercourse, painful bowel movements, and infertility; RANZCOG and ESHRE 2022 are the primary guideline sources in Australia
Fibroids — bulk symptoms, heavy menstrual bleeding, pressure
Ovarian cysts or endometriomas
Adhesions from past pelvic inflammatory disease or surgery
Pelvic congestion syndrome — postural aching that worsens when standing
Vulvodynia and vestibulodynia — burning, persistent vulval pain

Urological (both sexes):

Interstitial cystitis / bladder pain syndrome — bladder filling pain, urinary urgency and frequency without infection
Chronic prostatitis / chronic pelvic pain syndrome (men)
Recurrent urinary tract infections

Gastrointestinal:

Irritable bowel syndrome — the most common GI co-morbidity; affects 30–50% of those with CPP
Inflammatory bowel disease — distinguished by raised faecal calprotectin, PR bleeding, weight loss
Functional defecation disorders, chronic constipation, diverticular disease

Musculoskeletal:

Hypertonic pelvic floor — chronically tense levator ani and obturator internus muscles; a near-universal contributor found through internal palpation
Abdominal wall trigger points — Carnett test positive (pain worsens with abdominal wall tensing) indicates wall origin
Hip pathology — femoroacetabular impingement, labral tear
Coccydynia, pubic symphysis dysfunction, sacroiliac dysfunction

Neuropathic:

Pudendal neuralgia — perineal or genital burning that worsens with sitting and is relieved by sitting on a toilet; Nantes criteria
Post-surgical nerve entrapment — after Pfannenstiel incision, hernia repair, or Caesarean section

Central sensitisation: The nervous system, after prolonged nociceptive input, undergoes central sensitisation — the dorsal horn amplifies pain signals, descending inhibition weakens, and pain spreads beyond the original site. Hallmarks include allodynia (pain from non-painful stimuli), pain disproportionate to tissue findings, fatigue, sleep disruption, and spread to the thighs, lower back, and abdomen. Around 30–50% of people with CPP concurrently meet criteria for fibromyalgia, IBS, or migraine, reflecting a shared nociplastic biology.

Psychological and trauma: A history of childhood abuse, sexual assault, or intimate partner violence is reported in 30–50% of CPP cohorts, per As-Sanie et al. (Obstet Gynecol 2014). This is not a psychiatric dismissal — trauma drives real, measurable changes in HPA-axis function and peripheral pain processing. Trauma-informed care is mandated in ACSQHC Trauma-Informed Care principles and endorsed by Endometriosis Australia.

History — trauma-informed and comprehensive

Open the history with an explicit framing: “Many people I see with this kind of pain have had difficult experiences earlier in life that I’d like to ask about sensitively — you can decline any question and it won’t affect your care.” Document responses without judgement.

Key domains:

Pain character (SOCRATES: site, onset, character, radiation, associated features, timing, exacerbating and relieving factors, severity)
Bowel — stool consistency, PR bleeding, tenesmus, alternating bowel habit, painful defecation
Bladder — frequency, nocturia, urgency, dysuria, haematuria (red flag), retention
Sexual — superficial or deep dyspareunia, libido, sexual function
Menstrual and obstetric — cycle, contraception, previous pregnancies, perineal trauma, mode of delivery
Functional impact — work, sleep, mood, relationships, parenting
Mental health — depression, anxiety, PTSD, substance use
Past medical and surgical — previous pelvic surgery, STIs, known endometriosis, hip or back pathology
Trauma screen — explicit, sensitive questions about sexual, physical, or emotional abuse and intimate partner violence

Examination

A systematic examination includes:

General — BMI, posture, gait
Abdominal — scars, hernias, organomegaly, masses, Carnett test for abdominal wall trigger points
Pelvic (women) — vulval inspection, Q-tip vestibule test (vestibulodynia), bimanual for uterine size and mobility, adnexal mass, uterosacral nodularity (a pointer to endometriosis), and critically pelvic floor digital assessment — levator ani tone, trigger points, ability to voluntarily relax
DRE (men) — prostate size and tenderness, pelvic floor muscle assessment
Musculoskeletal — hip impingement tests (FADIR, FABER), sacroiliac joint provocation, coccyx palpation, pubic symphysis tenderness
Neurological — S2–S4 sensation, pudendal nerve tenderness over the ischial spine (Nantes criteria), straight-leg raise

Initial investigations

The first-line workup per RACGP and eTG:

Urine — dipstick, midstream culture (to exclude active UTI or haematuria)
β-hCG in any person of reproductive potential with a uterus
FBC and CRP (inflammation, anaemia)
Faecal calprotectin if bowel symptoms suggest IBD (Authority Required on MBS, or self-funded)
STI panel if at risk, per ASHM guidelines
Transvaginal ultrasound (women) — specialist gynaecological ultrasound strongly preferred for suspected endometriosis and adenomyosis; standard ultrasound frequently misses deep infiltrating disease
Scrotal and abdominal ultrasound (men) — to exclude testicular pathology, hernia, varicocoele

MRI pelvis is added when imaging suggests deep infiltrating endometriosis, adenomyosis, or pudendal or sacral pathology — usually specialist-requested. Laparoscopy is now reserved by ESHRE 2022 and RANZCOG for diagnostic-treatment combined intervention when empirical treatment has failed, or when specific indications apply.

B. Pelvic floor physiotherapy and pain education — the foundation

Pelvic floor down-training

The most common and actionable finding across almost all CPP phenotypes — endometriosis, interstitial cystitis, vulvodynia, and chronic prostatitis — is hypertonic pelvic floor muscles. The intervention is pelvic floor down-training and relaxation, performed by a trained women’s health or men’s health physiotherapist.

Kegel exercises — commonly prescribed for stress incontinence — actively worsen pain in hypertonic pelvic floor and must not be prescribed without an assessment confirming the pelvic floor is weak rather than tense. Referrals should explicitly request “assessment and relaxation, not strengthening.” Goldfinger (J Sex Med 2009) and Anderson (J Urol 2011) both demonstrate benefit for pelvic floor physiotherapy across sexual pain and chronic pelvic pain conditions.

Pelvic floor physiotherapy is funded under the GP Chronic Condition Management Plan (GPCCMP, item 965/967) for up to five allied-health sessions per year under item 10960. Request it at the first visit.

Pain neuroscience education

Explaining the biology of central sensitisation — “the nervous system, not the tissue, is producing and amplifying the pain signal” — reduces catastrophising, improves self-efficacy, and is itself a therapeutic intervention. The Pain Australia and PainHealth (University of Western Australia) websites provide patient-facing materials. Moseley’s Explain Pain is the standard resource.

Psychological input

Cognitive behavioural therapy (CBT) for chronic pain — addressing fear-avoidance, pain-related beliefs, and functional goals — has RCT evidence in chronic pelvic pain per Allaire (Am J Obstet Gynecol 2018). A Mental Health Treatment Plan (item 2715) opened at the first visit funds up to 10 psychology sessions per year and enables trauma-focused therapy where indicated. Comorbid depression and anxiety — present in approximately 50% of CPP patients — should be treated in parallel, not deferred.

C. Pharmacological management

What the evidence supports

Simple analgesics — paracetamol 1 g four times daily and NSAIDs (ibuprofen 400 mg three times daily, naproxen 250–500 mg twice daily, or mefenamic acid 500 mg three times daily for dysmenorrhoea) — provide flare relief but are not adequate sole long-term treatment.

Amitriptyline 10 mg nocte, titrated to 25–50 mg, is the most versatile systemic agent across CPP phenotypes. Per AMH and eTG, low-dose tricyclic antidepressants have established off-label use in chronic pelvic pain, interstitial cystitis, vulvodynia, and IBS. The PBS lists amitriptyline under the depression indication; off-label use for chronic pain is well-supported in Australian practice. Benefit typically plateaus by eight weeks.

Hormonal treatment (women with suspected endometriosis) — a therapeutic and empirical diagnostic trial. ESHRE 2022 supports starting a combined oral contraceptive pill in continuous regimen or progestin-only therapy before laparoscopy. Dienogest 2 mg daily (Visanne) is PBS Authority Required for confirmed endometriosis and must be prescribed as continuous (not cyclic) therapy. Progestin-only options include norethisterone or the levonorgestrel-releasing IUD (Mirena).

Duloxetine 30–60 mg daily — PBS-listed for major depression and generalised anxiety; off-label for chronic pain when mood and pain overlap, it provides dual benefit.

What evidence does not support

Gabapentin for unselected chronic pelvic pain — the large GaPP2 RCT (Horne, PAIN 2020) showed gabapentin was not more effective than placebo for chronic pelvic pain in women. Gabapentin is appropriate only for a clearly neuropathic phenotype (pudendal neuralgia, post-surgical nerve entrapment). SafeScript monitoring applies.

Long-term opioids — the SPACE trial (Krebs, JAMA 2018) and the Faculty of Pain Medicine ANZCA position both show no benefit of opioids over non-opioid therapy for chronic non-cancer pain, with significantly greater harm. Chronic pelvic pain is not an exception. Opioid-induced hyperalgesia can worsen pelvic pain.

D. Australian operations

MBS items

Key items for CPP management: standard consults (23, 36, 44), complex consults (132, 133), GPCCMP initial and review (965, 967), Mental Health Treatment Plan (2715, 2717), pelvic floor physiotherapy (10960 — up to 5 sessions), psychology under Better Access (items 80000–80020 — up to 10 sessions), transvaginal ultrasound (55700, 55703), scrotal/abdominal US, MRI pelvis (63491 range), diagnostic laparoscopy (35643, 35648), urinalysis (73529), urine MCS (69333), β-hCG (66695), FBC (65070), CRP (66512), faecal calprotectin (66617 — Authority), and STI PCR (69316).

PBS prescribing

Amitriptyline and NSAIDs — PBS general, no Authority required for the CPP use context. Dienogest (Visanne) — PBS Authority Required for endometriosis. Levonorgestrel IUD (Mirena) — PBS Authority Required. GnRH analogues (goserelin, leuprorelin) — PBS Authority Required, specialist-initiated. Gabapentin and pregabalin — PBS Authority Streamlined for neuropathic pain; SafeScript monitored. Duloxetine — PBS general (depression/GAD indication; off-label for pain). Relugolix-oestradiol-norethindrone (Ryeqo) — TGA-approved 2023; PBS status evolving.

Specialist referral pathways

Clinical scenario	Referral	Urgency
Red flags: suspected ectopic, torsion, acute abdomen, sepsis	Emergency department	Immediate
Suspected pelvic or GI malignancy	Gynaecology-oncology or colorectal surgery	Urgent (days)
Deep infiltrating endometriosis on imaging	Advanced laparoscopic gynaecologist	Soon
Refractory chronic prostatitis / CPPS	Urology or pelvic pain MDT	Routine
Suspected pudendal neuralgia (Nantes criteria)	Pain medicine	Routine
Severe psychological distress, suicidality	Psychiatry or 1800RESPECT	Urgent

Tertiary pelvic pain multidisciplinary teams exist at the Royal Hospital for Women (Sydney), Royal Women’s Hospital (Melbourne), and Queen Elizabeth Hospital (Adelaide).

Domestic and sexual abuse

1800RESPECT (1800 737 732) is the Australian national helpline for those experiencing family and domestic violence. Documentation of disclosures and mandatory reporting obligations (which vary by state) must be understood. The conversation, not the documentation, is the priority in the consultation.

E. Special populations

Men. Chronic prostatitis / chronic pelvic pain syndrome (CP/CPPS) accounts for most male CPP. The UPOINT framework — Urinary, Psychosocial, Organ-specific, Infection, Neurologic, Tenderness pelvic floor — guides treatment targeting. The urinary phenotype responds to an alpha-blocker (tamsulosin 400 mcg/day); the pelvic floor phenotype to physiotherapy. AUA 2022 guideline is the primary reference. A single empirical antibiotic trial (fluoroquinolone) is reasonable at first presentation if inflammatory CP/CPPS is suspected, but repeated empirical courses are not supported.

Adolescents. Endometriosis in adolescents is frequently dismissed as “bad periods.” The National Action Plan for Endometriosis (2018) calls for reduced diagnostic delay. An empirical hormonal trial is appropriate without requiring laparoscopy in adolescents with cyclical pelvic pain.

Pregnancy. Pelvic girdle pain and round ligament pain are common. Physiotherapy is first-line. Medication is constrained — paracetamol is the safest analgesic; NSAIDs are avoided from 20 weeks; opioids are avoided. Specialist obstetric physiotherapy is appropriate.

When to escalate

Refer immediately to the emergency department for:

Suspected ectopic pregnancy, ovarian torsion, or cauda equina syndrome
Acute abdomen with systemic compromise
Haematuria with suspected urological cancer, or postmenopausal bleeding

Refer urgently within days to weeks for:

Pelvic mass on examination or ultrasound
PR bleeding with weight loss or age over 50 (colorectal cancer screen)
Suspected ovarian, endometrial, or cervical cancer
Cauda equina symptoms (urinary retention, faecal incontinence, saddle anaesthesia)

Refer routinely to specialist pelvic pain MDT if multimodal therapy at three to six months has not produced measurable functional improvement.
