Pelvic Pain in Women: Common Causes, Diagnosis, and Treatment
Pelvic pain affects millions of women and has many possible causes, from period cramps to endometriosis to infections. Learn what's behind it, when it's an emergency, and what you can do about it.
TL;DR: Pelvic pain in women can be acute (sudden) or chronic (lasting 6 months or more), and its causes range from period cramps and ovulation pain to conditions like endometriosis, fibroids, ovarian cysts, and infections. Some causes require urgent medical attention. If pelvic pain is affecting your daily life, it deserves investigation, not dismissal.
You've probably heard some version of this before: "It's just cramps." "That's normal for women." "Take a painkiller and rest."
And maybe sometimes it is just cramps. But if you're reading this, it's probably because the pain you're feeling doesn't match those easy answers. It's lasting too long, happening at the wrong times, or hurting more than it should. You deserve better than a shrug.
Pelvic pain is one of the most common reasons women visit a doctor, and one of the most commonly dismissed. Let's change that. This guide will walk you through what pelvic pain actually is, what might be causing it, and what to do next.
What Is Pelvic Pain?
Pelvic pain is any pain you feel in your lower abdomen, below your belly button and between your hip bones. It can be sharp or dull, constant or intermittent (coming and going), and it can range from a mild ache to pain that stops you in your tracks.
The pelvis contains several organs, your uterus, ovaries, fallopian tubes, bladder, and part of your bowel. Pain can originate from any of these, which is partly why pinpointing the cause can take time.
Acute vs. Chronic Pelvic Pain
Doctors generally divide pelvic pain into two categories:
- Acute pelvic pain comes on suddenly and is often sharp or intense. It can signal something that needs immediate attention, like an ectopic pregnancy or a ruptured ovarian cyst.
- Chronic pelvic pain is pain that lasts for six months or longer. It may be constant or it may come and go, but it persists. Chronic pelvic pain affects an estimated 1 in 4 women at some point in their lives.
Both types matter. Both deserve answers.
Common Causes of Pelvic Pain
There are many possible reasons for pelvic pain. Here are the ones doctors see most often.
Period Cramps (Dysmenorrhea)
Dysmenorrhea (dis-men-oh-REE-ah) is the medical term for painful periods. During your period, your uterus contracts to shed its lining, and these contractions can cause cramping in your lower abdomen. For many women, this is mild and manageable. For others, the pain is severe enough to interfere with daily life.
There are two types:
- Primary dysmenorrhea, Cramps caused by the natural process of menstruation, with no underlying condition. These usually start a day or two before your period and ease within a few days.
- Secondary dysmenorrhea, Cramps caused by an underlying condition like endometriosis or fibroids. This pain tends to start earlier in the cycle, last longer, and worsen over time.
If your period pain has gotten worse over the years or doesn't respond to over-the-counter painkillers, that's worth investigating.
Ovulation Pain (Mittelschmerz)
Mittelschmerz (MIT-ul-shmerts, a German word meaning "middle pain") is a sharp or crampy pain on one side of your lower abdomen that happens around the middle of your menstrual cycle, when you ovulate (release an egg from your ovary). It usually lasts a few hours to a day or two and is generally harmless, though it can be uncomfortable.
Endometriosis
Endometriosis is a chronic condition where tissue similar to the lining of your uterus grows outside the uterus, on the ovaries, fallopian tubes, bowel, or other pelvic structures. This tissue responds to your hormonal cycle, causing inflammation, scarring, and often significant pain.
Endometriosis affects roughly 1 in 10 women of reproductive age and is one of the most common causes of chronic pelvic pain. It takes an average of 7 to 10 years to diagnose because its symptoms are so often dismissed as "normal" period pain.
Uterine Fibroids
Fibroids are non-cancerous growths that develop in or on the uterus. They're extremely common, up to 70 to 80% of women will develop at least one by age 50. Many fibroids cause no symptoms at all, but depending on their size and location, they can cause pelvic pain or pressure, heavy periods, frequent urination, and pain during sex.
Ovarian Cysts
Ovarian cysts are fluid-filled sacs that form on or inside the ovaries. Most are functional cysts (meaning they develop as a normal part of your menstrual cycle) and resolve on their own within a few weeks. However, larger cysts can cause a dull ache or sharp pain, especially if they rupture or twist the ovary (a condition called ovarian torsion, which is a medical emergency).
Polycystic Ovary Syndrome (PCOS)
PCOS is a hormonal condition that can cause multiple small follicles on the ovaries, irregular periods, and elevated androgen (male-type hormone) levels. While PCOS is more commonly associated with irregular cycles, acne, and weight changes, some women with PCOS also experience pelvic discomfort or pain.
Pelvic Inflammatory Disease (PID)
PID is an infection of the reproductive organs, usually the uterus, fallopian tubes, and ovaries, most often caused by sexually transmitted infections (STIs) like chlamydia or gonorrhea that spread upward from the cervix. Symptoms include pelvic pain, unusual vaginal discharge, pain during sex, fever, and painful urination. If left untreated, PID can cause scarring and long-term complications, including infertility.
If you think you might have an STI or PID, getting tested and treated early makes a real difference. (Read more in our guide to STIs.)
Urinary Tract Infections (UTIs)
A UTI is an infection in your urinary system, most often the bladder. While the hallmark symptoms are burning during urination and needing to pee frequently, UTIs can also cause pain or pressure in your lower pelvis. Women are far more likely than men to get UTIs because of the shorter distance between the urethra and the bladder.
Ectopic Pregnancy
An ectopic pregnancy happens when a fertilized egg implants outside the uterus, most commonly in a fallopian tube. This is a medical emergency. As the pregnancy grows, it can cause the tube to rupture, leading to life-threatening internal bleeding. Symptoms include sharp pain on one side of the pelvis, vaginal bleeding, dizziness, and shoulder pain. More on recognizing this below.
Adenomyosis
Adenomyosis (ad-en-oh-my-OH-sis) is a condition where the tissue that normally lines the uterus grows into the muscular wall of the uterus. Think of it as endometriosis's less-talked-about cousin. It can cause an enlarged uterus, heavy and prolonged periods, and significant pelvic pain or cramping. It's most common in women in their 30s and 40s.
Pelvic Floor Dysfunction
Your pelvic floor is a group of muscles that supports your bladder, uterus, and rectum, like a hammock at the bottom of your pelvis. When these muscles are too tight, too weak, or don't coordinate properly, it's called pelvic floor dysfunction. This can cause chronic pelvic pain, pain during sex, difficulty with urination or bowel movements, and a feeling of heaviness or pressure. It's more common than people realize and is very treatable.
When Pelvic Pain Is an Emergency
Most pelvic pain isn't an emergency, but some situations require immediate medical care. Go to the emergency room or call for help if you experience:
- Sudden, severe pelvic pain, especially on one side
- Pelvic pain with vaginal bleeding if you're pregnant or could be pregnant (signs of ectopic pregnancy or miscarriage)
- Dizziness, fainting, or shoulder pain along with pelvic pain (can indicate internal bleeding from a ruptured ectopic pregnancy)
- Fever above 38.3 C (101 F) with pelvic pain (may suggest a serious infection like PID or appendicitis)
- Pain so severe you can't stand, walk, or find a comfortable position
It's also worth knowing that appendicitis can mimic pelvic pain, especially in women. The pain typically starts around the belly button and moves to the lower right side. If you notice this pattern along with nausea, vomiting, or fever, seek emergency care.
When in doubt, err on the side of caution. It's always better to be checked and reassured than to wait too long.
How Pelvic Pain Is Diagnosed
Because so many conditions can cause pelvic pain, finding the answer often takes more than one step. Here's what the diagnostic process typically looks like:
Medical History and Physical Exam
Your doctor will start by asking detailed questions about your pain: where exactly it is, when it started, what makes it better or worse, whether it's related to your menstrual cycle, and whether you have other symptoms. A pelvic exam (where a healthcare provider gently examines your reproductive organs) may be done to check for tenderness, masses, or abnormalities.
Imaging
- Ultrasound is usually the first imaging test. A transvaginal ultrasound (where a small probe is inserted into the vagina) can show fibroids, ovarian cysts, signs of adenomyosis, and sometimes endometriosis.
- MRI may be used if more detailed images are needed, particularly for adenomyosis or deep endometriosis.
Lab Tests
Blood tests, urine tests, and STI screenings can help rule out infections, pregnancy, and other conditions.
Laparoscopy
For conditions like endometriosis, the definitive diagnosis often requires a laparoscopy (lap-ah-ROS-koh-pee), a minimally invasive surgical procedure where a thin camera is inserted through a small incision near your belly button so the surgeon can look directly at your pelvic organs. This is considered the gold standard for diagnosing endometriosis.
Getting a diagnosis can take time
If your first appointment doesn't give you a clear answer, that doesn't mean nothing is wrong. Pelvic pain can be genuinely complex to diagnose, and some conditions don't show up on standard tests. Advocate for yourself, keep a pain diary, and don't hesitate to ask for a referral to a specialist (like a gynecologist or pelvic pain specialist).
Treatment Options
Treatment depends entirely on what's causing your pelvic pain. There's no one-size-fits-all approach.
For period cramps and ovulation pain
- Over-the-counter pain relief (ibuprofen or naproxen work best because they reduce prostaglandins, the chemicals that cause uterine contractions)
- Hormonal birth control to regulate or suppress your cycle
- Heat therapy (a hot water bottle or heating pad on your lower abdomen)
For endometriosis and adenomyosis
- Hormonal treatments to slow tissue growth (birth control pills, progesterone therapy, GnRH agonists)
- Pain management with NSAIDs (non-steroidal anti-inflammatory drugs)
- Laparoscopic surgery to remove endometrial implants
- In severe cases, hysterectomy (surgical removal of the uterus) may be considered
For fibroids
- Monitoring if they're small and not causing symptoms
- Hormonal treatments to shrink them
- Procedures like uterine artery embolization (cutting off the blood supply to the fibroid) or surgical removal (myomectomy)
For infections (PID, UTIs)
- Antibiotics, and completing the full course is essential
- Partner treatment for STI-related PID to prevent reinfection
For ovarian cysts
- Watchful waiting for small, functional cysts
- Surgery if a cyst is large, persistent, or causing complications
For pelvic floor dysfunction
- Pelvic floor physiotherapy, a specialized type of physical therapy that is often highly effective
- Relaxation techniques and biofeedback
- In some cases, medication for muscle spasms
Managing Pelvic Pain Day to Day
While you work toward a diagnosis or alongside your treatment plan, there are things you can do to manage pelvic pain:
- Track your pain, Note when it happens, how long it lasts, how severe it is (on a scale of 1 to 10), and what you were doing. Patterns can help your doctor enormously.
- Heat therapy, Applying warmth to your lower abdomen can relax pelvic muscles and reduce cramping.
- Gentle movement, Light exercise like walking, yoga, or swimming can help by increasing blood flow and releasing endorphins (your body's natural painkillers).
- Stress management, Chronic pain and stress feed into each other. Techniques like deep breathing, meditation, or even just making time for rest can help break that cycle.
- Pain medication, Use as directed. NSAIDs like ibuprofen are often more effective for pelvic pain than acetaminophen (paracetamol) because they target inflammation.
- Communicate with your support system, Pain that others can't see can feel isolating. Letting the people around you know what you're dealing with makes a difference.
Your Pain Is Not "Just Cramps"
If there is one thing to take away from this post, let it be this: pelvic pain that disrupts your life is not something you should just accept.
Too many women spend years being told their pain is normal, only to eventually discover a treatable condition that could have been addressed much sooner. The normalization of women's pain, by society, by healthcare systems, and sometimes by women themselves, costs real years of quality of life.
You know your body. If something feels wrong, it's worth pursuing. Ask questions. Push for answers. Get a second opinion if you need to. You are not being dramatic. You are being your own best advocate.
