High-yield

Chronic pelvic pain lasts at least 6 months and is often multifactorial; evaluate gynecologic, urologic, GI, musculoskeletal, neuropathic, and psychosocial sources, with transvaginal ultrasound as first-line imaging.
Interstitial cystitis/bladder pain syndrome: pain as the bladder fills, relief with voiding, urgency and frequency, sterile urine; cystoscopy may show Hunner lesions.
IC/BPS treatment escalates from diet and self-care to pelvic floor therapy, oral amitriptyline or pentosan polysulfate (retinal exams for maculopathy), then intravesical DMSO or heparin–lidocaine.
Pelvic congestion syndrome causes dull pain worse with standing and after intercourse from dilated ovarian veins; embolization or progestins help.
A positive Carnett sign (pain same or worse with tensed abdominal muscles) means abdominal wall pain, treated with trigger point injection.
Pudendal neuralgia causes perineal pain worse with sitting and relieved by standing; a pudendal nerve block confirms it.
Provoked vestibulodynia is diagnosed by cotton-swab pain at the vestibule after excluding infection, dermatoses, and atrophy.
Genitourinary syndrome of menopause: moisturizers and lubricants first, then low-dose vaginal estrogen; ospemifene or vaginal DHEA are alternatives. Vaginismus responds to pelvic floor therapy, dilators, and CBT.
Deep dyspareunia suggests endometriosis or adnexal disease; diagnostic laparoscopy is used when imaging and empiric multimodal therapy fail.

Overview and evaluation

Definition. Chronic pelvic pain is pain perceived in the pelvis for at least 6 months, cyclic or noncyclic, severe enough to impair function or prompt care. It is frequently multifactorial: an initial visceral source (endometriosis, bladder, bowel) can recruit pelvic floor muscle spasm and central sensitization, so several generators often coexist.

History and exam. Relate the pain to menses, voiding, defecation, intercourse, posture, and sitting, and ask about mood, sleep, and past abuse. Examine the abdominal wall (Carnett sign), the vestibule with a cotton swab, and the pelvic floor with a single-digit exam before any bimanual exam, so each structure is tested on its own.

Initial tests. Pregnancy test, urinalysis and urine culture, gonorrhea and chlamydia NAAT, and transvaginal ultrasound, the first-line imaging test. Red flags such as postmenopausal bleeding, weight loss, hematuria, or rectal bleeding require targeted evaluation for malignancy.

Chronic pelvic pain by system

System	Condition	Key clue	Treatment
Gynecologic	Endometriosis	Cyclic pain, dyschezia, deep dyspareunia, uterosacral nodularity	Hormonal suppression; laparoscopic excision
Gynecologic	Pelvic congestion	Ache worse standing and late in the day; dilated pelvic veins	Progestins, GnRH agonist, embolization
Urologic	IC/bladder pain syndrome	Pain with filling, relief with voiding, sterile urine	Diet, PT, oral and intravesical agents
GI	Irritable bowel syndrome	Pain linked to defecation, altered stool form or frequency	Diet, fiber, antispasmodics
Musculoskeletal	Abdominal wall pain	Positive Carnett sign	Trigger point injection
Neuropathic	Pudendal neuralgia	Worse sitting, relieved standing	Nerve block, neuropathic agents

Gynecologic and urologic causes

Endometriosis, adenomyosis, adhesions. Endometriosis produces cyclic pain with dysmenorrhea, dyschezia, deep dyspareunia, and infertility; exam may show uterosacral nodularity or a fixed retroverted uterus. It can be treated empirically with hormonal suppression, while laparoscopy with biopsy remains definitive. A boggy, tender, enlarged uterus suggests adenomyosis, and prior PID or pelvic surgery suggests adhesions or chronic PID.

Pelvic congestion syndrome. Multiparous premenopausal women describe a dull ache that worsens with prolonged standing, late in the day, and after intercourse. Dilated, refluxing ovarian and pelvic veins are shown by Doppler ultrasound, MRI, or venography. Options include medroxyprogesterone or other progestins, GnRH agonists, and ovarian vein embolization.

Interstitial cystitis/bladder pain syndrome (IC/BPS). Suprapubic pain or pressure builds as the bladder fills and eases after voiding, with urgency, frequency, and nocturia. Urine is sterile, and flares follow menses, intercourse, stress, or foods such as coffee, citrus, and spicy dishes. The diagnosis is clinical and made by exclusion of infection and, when hematuria or smoking raises concern, bladder cancer. Cystoscopy is not required but may reveal Hunner lesions.

Self-careEducation, trigger-food avoidance, stress reduction
Pelvic floor physical therapyManual myofascial release; avoid Kegel strengthening
Oral agentsAmitriptyline, hydroxyzine, cimetidine, pentosan polysulfate
Intravesical therapyDMSO or heparin with lidocaine
Cystoscopic treatmentFulguration or steroid injection of Hunner lesions

Pentosan polysulfate causes a pigmentary maculopathy; obtain a baseline retinal exam and repeat periodically. Long-term antibiotics and intravesical BCG have no role in IC/BPS.

GI, musculoskeletal, neuropathic, and psychosocial causes

Irritable bowel syndrome. Recurrent abdominal pain at least 1 day per week for 3 months, associated with at least two of: defecation, a change in stool frequency, or a change in stool form (Rome IV), often with bloating. Bleeding, weight loss, anemia, or onset after age 50 require colonoscopy before the label is applied.

Pelvic floor myofascial pain. Taut, tender bands in the levator ani reproduce the patient's pain on single-digit vaginal palpation, often with dyspareunia and voiding or defecatory dysfunction. Pelvic floor physical therapy aims at relaxation and myofascial release; trigger point injections help selected patients. Kegel strengthening worsens a hypertonic pelvic floor.

Abdominal wall pain. Trigger points and anterior cutaneous nerve entrapment, often near a Pfannenstiel scar, cause fingertip-localized pain. With a positive Carnett sign, pain stays the same or worsens when the patient tenses the abdominal wall by lifting the head or legs; visceral pain lessens because the tensed muscles shield the viscera. A trigger point injection of local anesthetic, with or without steroid, is diagnostic and therapeutic. Ilioinguinal and iliohypogastric entrapment after low transverse incisions behaves similarly.

Pudendal neuralgia. Burning or stabbing pain in the vulva, perineum, or rectum worsens with sitting, eases on standing or sitting on a toilet seat, does not wake the patient, and occurs without objective sensory loss. Prolonged cycling, childbirth, pelvic surgery, and long hours of sitting are risk settings. Relief from an anesthetic pudendal nerve block supports the diagnosis; management includes neuropathic agents, physical therapy, repeat blocks, and surgical decompression for refractory cases.

Psychosocial factors. Depression, anxiety, PTSD, and past physical or sexual abuse are common and amplify pain. Screen every patient; CBT and SNRIs or TCAs treat mood and pain together.

Dyspareunia: entry versus deep

Provoked vestibulodynia. The most common cause of entry dyspareunia in premenopausal women: burning at the vestibule with tampon insertion or intercourse, reproduced by light cotton-swab pressure around the hymenal ring. It is a diagnosis of exclusion after infection, dermatoses such as lichen sclerosus, and atrophy are ruled out. Treatment includes irritant avoidance, topical lidocaine before intercourse, pelvic floor therapy, CBT, and TCAs or gabapentinoids, with vestibulectomy for refractory cases.

Genitourinary syndrome of menopause. Hypoestrogenism causes dryness, burning, dyspareunia, urgency, and recurrent UTI, with pale, thin mucosa, lost rugae, and vaginal pH above 4.5. Regular moisturizers and coital lubricants come first, then low-dose vaginal estrogen (cream, tablet, or ring), which needs no added progestin. Alternatives are oral ospemifene, a SERM that can cause hot flashes and carries VTE risk, and vaginal prasterone (DHEA).

Vaginismus. Classified in DSM-5 as genito-pelvic pain/penetration disorder, it is involuntary pelvic floor spasm with attempted penetration, driven by fear of pain, with an otherwise normal exam. Pelvic floor physical therapy, graduated self-inserted dilators, and CBT or sex therapy are effective.

Deep dyspareunia. Pain with deep thrusting points above the vagina: endometriosis, adnexal cysts or masses, a fixed retroverted uterus from adhesions, adenomyosis, chronic PID, IC/BPS, or pelvic congestion. Exam and transvaginal ultrasound guide the evaluation.

Multimodal management

Treat every generator. Combine NSAIDs, hormonal suppression for cyclic pain, neuropathic agents (TCAs, SNRIs, gabapentinoids), pelvic floor physical therapy, and psychological therapy. Avoid long-term opioids.

Laparoscopy. When imaging and empiric therapy fail, diagnostic laparoscopy can identify and excise endometriosis or lyse adhesions.

Hysterectomy relieves chronic pelvic pain only when the pain clearly arises from the uterus and childbearing is complete; many patients with multifactorial pain continue to hurt afterward.
