Pelvic Pain: When to See a Doctor, What Causes It, and How It's Treated

What Is Pelvic Pain and Why Does It Show Up Differently in Women?

Pelvic pain sits in the lower abdomen, between your hip bones and below your navel. In women, that space contains the uterus, ovaries, fallopian tubes, bladder, bowel, and a dense web of nerves and connective tissue. Any one of those structures can generate pain, and hormones change the threshold at which they do.

Your estrogen and progesterone levels shift across the menstrual cycle, across reproductive life stages, and into menopause. Those shifts alter prostaglandin production, smooth muscle tone, and central pain sensitization. A pain signal that originates in the uterus may be amplified or suppressed depending on where you are in your cycle or whether you are postmenopausal. This is why pelvic pain is genuinely a women's-health specialty topic, not a generic abdominal complaint.

Chronic pelvic pain affects approximately 15% of women of reproductive age in the United States, accounting for roughly 10% of all outpatient gynecology referrals. That number almost certainly underestimates the true burden because many women normalize the pain or receive no formal diagnosis for years.

When Pelvic Pain Is a Medical Emergency

Some presentations need 911 or an emergency department visit right now, not a scheduled appointment.

Go to the ER or Call 911 If You Have

• Sudden, severe pelvic pain that comes on in seconds or minutes (suggests ovarian torsion or ruptured ectopic pregnancy)
• Pelvic pain plus fever above 38.5°C (101.3°F), which may indicate pelvic inflammatory disease (PID) with abscess or appendicitis
• Fainting, dizziness, or a rapid heart rate alongside pelvic pain (signs of internal bleeding)
• A positive pregnancy test with one-sided sharp pain and shoulder tip pain (ectopic pregnancy until proven otherwise)
• Rigid, board-like abdomen

Ruptured ectopic pregnancy remains a leading cause of first-trimester maternal death, which is exactly why ACOG classifies undiagnosed first-trimester pelvic pain as urgent. If you are pregnant or could be pregnant and your pain is severe, do not wait.

Urgent (Same-Day or Next-Day) Appointment

• Fever below 38.5°C with pelvic pain and unusual vaginal discharge (possible PID)
• Pain severe enough to prevent walking or sleeping
• New pelvic pain after a recent intrauterine device (IUD) insertion
• Pelvic pain with urinary retention or inability to pass stool

Common Causes of Pelvic Pain by Life Stage

The most likely cause of your pelvic pain depends on where you are in reproductive life. Below is a stage-by-stage breakdown.

Reproductive Years (Roughly Ages 15 to 45)

Dysmenorrhea (painful periods). Primary dysmenorrhea, pain without a structural cause, affects up to 84% of adolescents and young women and is driven by excess prostaglandin E2 and F2-alpha released from the uterine lining. Secondary dysmenorrhea points to an underlying condition such as endometriosis or fibroids.

Endometriosis. Endometrial-like tissue outside the uterus triggers inflammation, adhesions, and deep pelvic pain that often correlates with menstruation but can be constant. Globally, endometriosis affects roughly 190 million women and girls, yet the average diagnostic delay from symptom onset to confirmed diagnosis remains 7 to 10 years. Pain is typically cyclic at first, then may become non-cyclic as adhesions form.

Polycystic ovary syndrome (PCOS). Ovarian enlargement, follicular cysts, and chronic low-grade inflammation contribute to pelvic discomfort in PCOS. The pain is often described as a dull ache rather than sharp stabbing, and it does not always track with the cycle precisely because ovulation is irregular.

Ovarian cysts. Functional cysts develop and resolve across most menstrual cycles without causing symptoms. A cyst that ruptures produces sudden, often one-sided pain. Torsion (the ovary twisting on its pedicle) produces severe, escalating pain and is a surgical emergency. Ovarian torsion accounts for approximately 3% of gynecologic emergencies.

Pelvic inflammatory disease (PID). Ascending infection, most often from chlamydia or gonorrhea, inflames the uterus, tubes, and ovaries. The classic triad is lower abdominal pain, cervical motion tenderness on examination, and mucopurulent discharge. The CDC 2021 STI Treatment Guidelines recommend outpatient antibiotic therapy for mild-to-moderate PID but hospitalization for severe cases, suspected abscess, or pregnancy.

Interstitial cystitis / bladder pain syndrome. Pain perceived as pelvic or suprapubic, made worse by bladder filling and relieved by urination, affects women at a rate roughly five times higher than men. It is frequently misdiagnosed as recurrent UTIs.

Fibroids (uterine leiomyomata). Fibroids affect up to 70% of white women and 80% of Black women by age 50. Submucosal and large intramural fibroids cause heavy bleeding, pelvic pressure, and pain. Subserosal fibroids may cause positional discomfort or urinary frequency.

Trying to Conceive and Pregnancy

During active conception attempts, pelvic pain may come from ovarian stimulation (especially with medications like clomiphene or gonadotropins), implantation cramping, or early pregnancy complications. Round ligament pain begins as the uterus grows from around 12 to 14 weeks and feels like a sharp, stabbing sensation to one or both sides with sudden movements.

Any first-trimester pelvic pain requires ectopic pregnancy exclusion. An ectopic that has not yet ruptured may produce only mild, one-sided cramping, which is easy to dismiss. A quantitative beta-hCG paired with transvaginal ultrasound is the standard diagnostic approach. ACOG Practice Bulletin 193 outlines the full diagnostic algorithm for ectopic pregnancy.

Placental abruption and preterm labor produce pelvic or lower abdominal pain in the second and third trimesters and require immediate obstetric evaluation.

Postpartum and Lactation

After delivery, afterpains (uterine involution cramps) are normal for several days and are stronger with breastfeeding because oxytocin release accelerates uterine contraction. Persistent pain beyond two weeks, especially with fever or abnormal lochia, raises concern for endometritis or retained products of conception.

Pelvic floor dysfunction, including levator ani spasm and pudendal nerve irritation from childbirth trauma, can cause pelvic pain for months postpartum. Referral to a pelvic floor physical therapist is appropriate when pain persists past six weeks.

Perimenopause (Roughly Ages 40 to 52)

New or changing pelvic pain in the years around the final menstrual period deserves careful evaluation. Fibroid growth can accelerate in perimenopause due to estrogen fluctuations before the decline, and adenomyosis (endometrial glands within the uterine muscle) often becomes symptomatic during this stage.

Ovarian function declines erratically in perimenopause, and irregular ovulation can produce mid-cycle pain that was never bothersome before. Any postmenopausal bleeding alongside pelvic pain must prompt endometrial evaluation to rule out uterine cancer.

Postmenopause

After the final menstrual period, reproductive-organ pain should be absent. New pelvic pain in a postmenopausal woman is not normal and warrants investigation for:

• Genitourinary syndrome of menopause (GSM): vaginal atrophy can cause dyspareunia and a low-grade pelvic ache
• Ovarian cancer: often presents with vague lower abdominal discomfort, bloating, and urinary urgency
• Pelvic organ prolapse: pressure and heaviness in the vaginal introitus, typically worse with standing
• Colorectal pathology: constipation and diverticular disease become more common after menopause

The American Cancer Society estimates that approximately 19,680 new cases of ovarian cancer will be diagnosed in the U.S. In 2024, and persistent, unexplained pelvic symptoms in postmenopausal women should not be attributed to aging without imaging and clinical assessment.

Non-Gynecologic Causes That Are Often Missed

The pelvis is shared territory. Conditions outside the reproductive organs cause pelvic pain at least as often as gynecologic ones, and the two can coexist.

Irritable bowel syndrome (IBS). IBS affects roughly twice as many women as men. Cramping, bloating, and altered bowel habits can mimic endometriosis or ovarian pain almost exactly.

Pelvic floor myofascial pain. Hypertonic (too-tight) pelvic floor muscles produce diffuse pelvic pain, dyspareunia, and urinary symptoms without any visible structural disease. This is one of the most under-diagnosed causes of chronic pelvic pain in women.

Appendicitis. Right-sided lower abdominal pain, nausea, and fever. The classic periumbilical-to-right-iliac-fossa migration does not always occur in women, making diagnosis harder. A 2018 BMJ review noted that women of reproductive age face a higher rate of negative appendectomy than men largely because ovarian pathology mimics appendicitis.

Hernia. An inguinal or femoral hernia can cause groin and pelvic pain that worsens with standing or exertion.

Musculoskeletal causes. Sacroiliac joint dysfunction, hip pathology, and pubic symphysis pain all refer into the pelvic region and are more common in women who have had pregnancies.

How Pelvic Pain Is Diagnosed

Diagnosis is a process, not a single test. Your clinician will combine your history, physical examination, and selected investigations.

History: What Your Clinician Needs to Know

Bring this information to your appointment:

• Where exactly is the pain, and does it radiate?
• Is it cyclic (tied to your period or ovulation) or constant?
• How long has it been present? Acute means less than 3 months; chronic means 6 months or longer.
• What makes it better or worse (position, urination, bowel movements, sex, movement)?
• Your full menstrual history, including cycle regularity, flow, and whether sex is painful
• Pregnancy history, including any ectopic pregnancies or losses
• Sexual history and STI testing history
• Bowel and bladder symptoms

A practical three-axis framework for the clinical assessment of female pelvic pain: (1) Cyclic vs. Non-cyclic to distinguish hormone-driven from structural or non-gynecologic causes; (2) Acute vs. Chronic to calibrate urgency; (3) Localized vs. Diffuse to narrow the organ system. Applying all three axes before ordering tests cuts unnecessary imaging and speeds time to diagnosis.

Physical Examination

A pelvic exam is standard. Your clinician will assess for cervical motion tenderness (a sign of PID or ectopic), uterine size and mobility, adnexal masses, and pelvic floor muscle tone. Tenderness on single-digit palpation of specific pelvic floor muscles points toward myofascial pain.

Investigations

| Test | What It Rules In or Out | |---|---| | Transvaginal ultrasound | Ovarian cysts, fibroids, free fluid (blood), uterine anomalies | | Beta-hCG (urine or serum) | Pregnancy, ectopic pregnancy | | Cervical swabs (NAAT) | Chlamydia, gonorrhea (PID) | | Urinalysis and urine culture | UTI, interstitial cystitis | | CBC, CRP, ESR | Infection, inflammation | | CA-125 | Adjunct for ovarian pathology (low specificity alone) | | MRI pelvis | Deep infiltrating endometriosis, adenomyosis, complex masses | | Diagnostic laparoscopy | Gold standard for endometriosis diagnosis |

The ASRM practice committee confirms that laparoscopy remains the only definitive method to diagnose and stage endometriosis, though MRI has improved detection of deep infiltrating disease.

Treatment for Pelvic Pain: Matching the Cause to the Fix

No single treatment works for all pelvic pain. The approach depends on the underlying cause, your reproductive goals, and your life stage.

Medications

NSAIDs. Naproxen sodium 550 mg twice daily or ibuprofen 400 to 600 mg every 6 hours, started 1 to 2 days before expected menstruation, reduces prostaglandin-mediated pain from dysmenorrhea by up to 70% in clinical trials. A Cochrane review of NSAIDs for primary dysmenorrhea found they were significantly more effective than placebo.

Hormonal therapy. Combined oral contraceptives, the levonorgestrel IUD (Mirena, Liletta), progestins, and GnRH agonists (leuprolide) are the mainstay of hormonal management for endometriosis and adenomyosis. ACOG Practice Bulletin 114 endorses empirical hormonal suppression when endometriosis is clinically suspected but laparoscopy is not yet performed.

Dienogest 2 mg daily, a progestin with selective endometrial activity, is approved in many countries (though not yet the U.S.) and shows comparable efficacy to GnRH agonists without the bone density loss. In postmenopausal women with GSM-related pain, low-dose vaginal estradiol relieves genitourinary pain without meaningful systemic absorption and is supported by The Menopause Society's 2023 position statement.

Antibiotics for PID. The CDC recommends outpatient treatment with ceftriaxone 500 mg IM single dose, doxycycline 100 mg orally twice daily for 14 days, and metronidazole 500 mg orally twice daily for 14 days per the 2021 STI Treatment Guidelines.

Pelvic Floor Physical Therapy

Pelvic floor PT is first-line for myofascial pelvic pain and an important adjunct for endometriosis, interstitial cystitis, and postpartum pelvic pain. A specialist uses internal and external manual techniques to release hypertonic muscles, retrain coordination, and address scar tissue. Sessions typically run 45 to 60 minutes, with measurable improvement in most women by 6 to 8 sessions.

Surgical Options

Laparoscopic excision of endometriosis lesions reduces pain more effectively than ablation alone in most studies. A landmark randomized trial by Abbott et al. Published in Fertility and Sterility found that laparoscopic surgical treatment of endometriosis reduced pain in 80% of participants at six months compared to diagnostic laparoscopy alone.

Myomectomy (removal of fibroids while preserving the uterus) is appropriate for women who want to maintain fertility. Hysterectomy resolves pain from adenomyosis or fibroids definitively but ends reproductive potential. Ovarian cystectomy is preferred over oophorectomy for benign ovarian cysts to preserve ovarian reserve.

Integrative Approaches

Evidence-backed adjuncts include:

• Transcutaneous electrical nerve stimulation (TENS) for dysmenorrhea
• Mindfulness-based stress reduction, which reduced pain interference scores in a 2017 trial in Obstetrics and Gynecology (Wolters Kluwer journal via journals.lww.com)
• Dietary modifications reducing arachidonic acid intake (limiting red meat and dairy), which some women with endometriosis report as helpful, though controlled trial data remain limited

Pregnancy, Lactation, and Contraception Considerations

This section applies to all medications used for pelvic pain management.

NSAIDs. Avoid ibuprofen and naproxen after 20 weeks of pregnancy due to risk of premature closure of the ductus arteriosus and fetal renal impairment. The FDA strengthened this warning in 2020. In the first trimester, NSAID use is associated with a small increased risk of miscarriage. NSAIDs pass into breast milk in small amounts; short-term ibuprofen use while breastfeeding is generally considered compatible by the American Academy of Pediatrics, but discuss with your prescriber.

Combined hormonal contraceptives (CHC). CHCs used for endometriosis or dysmenorrhea are contraindicated in pregnancy. If you are trying to conceive, discuss progestin-only or non-hormonal alternatives with your clinician.

GnRH agonists (leuprolide, elagolix). These drugs are contraindicated in pregnancy. Elagolix (Orilissa) carries FDA Pregnancy Category X status; it requires reliable non-hormonal contraception during use because GnRH suppression does not reliably prevent ovulation in all cycles. Women must use barrier contraception throughout treatment.

Doxycycline (used in PID treatment). Contraindicated in pregnancy (FDA Category D) due to effects on fetal bone and tooth development. Alternative PID regimens exist for pregnant women; discuss with your provider immediately if you are pregnant and diagnosed with PID.

Progestins for endometriosis. Dienogest and medroxyprogesterone are not approved for use in pregnancy. All hormonal suppressants for endometriosis require reliable contraception because they do not reliably prevent pregnancy while suppressing ovarian function in all women.

If you are postmenopausal and using low-dose vaginal estradiol for GSM-related pelvic pain, no contraception is needed, and the treatment does not affect pregnancy risk. Systemic absorption is minimal at standard vaginal doses.

Who This Is Right for and Who Should Consider Different Approaches

Women Who Can Benefit Most from Prompt Evaluation

• Any woman with new pelvic pain that has lasted more than two menstrual cycles without a clear explanation
• Adolescents with dysmenorrhea that does not respond to NSAIDs after two to three cycles (possible early endometriosis)
• Women with painful sex (dyspareunia) at any life stage
• Women who are postmenopausal with any new pelvic symptom

When a Watchful-Waiting Approach Is Reasonable

• A simple ovarian cyst smaller than 5 cm in a premenopausal woman with mild symptoms may be observed with repeat ultrasound in 6 to 12 weeks per ACOG guidance on adnexal masses
• Mild round ligament pain in pregnancy from 12 to 28 weeks without other symptoms
• Afterpains in the first few postpartum days, manageable with ibuprofen

When to Seek a Specialist

A gynecologist, urogynecologist, or pelvic pain specialist is appropriate when:

• Pain is chronic (lasting 6 or more months)
• Two first-line treatments have not worked
• You have symptoms suggesting endometriosis, interstitial cystitis, or pelvic floor dysfunction
• You are postmenopausal with unexplained pelvic pain after basic evaluation

The Evidence Gap: What We Do Not Know Yet

Women have been systematically under-represented in pain research for decades. Most chronic pelvic pain trials enrolled predominantly reproductive-age women, leaving a thin evidence base for managing pelvic pain in postmenopausal women and for women over 50 who are not on hormone therapy. The intersection of pelvic pain with Black women's health is particularly under-studied, despite Black women experiencing fibroids at roughly 2 to 3 times the rate of white women and facing longer delays to fibroid treatment.

What we extrapolate rather than directly know: pain sensitization data in perimenopause is largely derived from small observational studies rather than randomized trials. The efficacy of TENS, dietary modification, and mindfulness for non-dysmenorrhea pelvic pain in postmenopausal women is not well-established from primary data.
