Pelvic pain can feel like a dull pressure, a stubborn cramp, a sharp stab or an unpleasant sensation that seems to move between the lower abdomen, groin, hips and back. Sometimes the explanation is relatively simple, such as a strained muscle or constipation. In other cases, sudden pelvic pain can signal a medical emergency.
The pelvis contains parts of the digestive, urinary and reproductive systems, along with bones, joints, nerves and pelvic floor muscles. That crowded neighborhood explains why two people with pain in almost the same spot may have completely different conditions. It also explains why diagnosing pelvic pain occasionally resembles detective workexcept the detective may order blood tests and an ultrasound.
Medical note: This article provides general educational information and cannot diagnose the cause of pelvic pain. Sudden, severe or worsening pain should be evaluated promptly by a qualified healthcare professional.
What Is Pelvic Pain?
Pelvic pain occurs below the belly button and between the hips. It may remain in one small area, spread across the lower abdomen or radiate into the lower back, thighs, rectum, penis, testicles, vagina or vulva.
Acute pelvic pain begins suddenly and may last minutes, hours or days. Chronic pelvic pain persists or repeatedly returns over several months. Chronic pain may come from one identifiable condition, but it can also involve overlapping problemsfor example, endometriosis combined with pelvic floor tightness or bladder pain syndrome.
The timing of the pain provides valuable clues. Pain linked to urination suggests a urinary cause. Pain that changes after a bowel movement may involve the digestive system. Cyclic pain can be associated with ovulation, menstruation, endometriosis or adenomyosis. Pain after lifting or exercise may point toward a hernia or musculoskeletal injury.
24 Possible Causes of Pelvic Pain
Causes That Can Affect Men and Women
-
1. Appendicitis
Appendicitis usually produces pain that begins near the belly button and moves toward the lower-right abdomen. The pain may worsen with movement, coughing or pressure. Nausea, vomiting, loss of appetite and fever can occur. Because a ruptured appendix can cause a dangerous infection, rapidly worsening right-sided pain needs urgent assessment.
-
2. Urinary Tract Infection
A urinary tract infection, or UTI, can cause pressure or aching low in the pelvis. Other symptoms may include burning during urination, frequent bathroom trips, cloudy urine, strong-smelling urine or blood in the urine. Fever, chills, nausea or pain in the side or back can indicate that the infection has reached a kidney.
-
3. Kidney Stones
A kidney stone may cause severe pain that travels from the back or side into the lower abdomen, pelvis or groin. The discomfort often arrives in waves rather than remaining steady. Nausea, vomiting, urinary urgency and blood in the urine may accompany it. A stone may be tiny, but it can produce pain with the confidence of something the size of a bowling ball.
-
4. Interstitial Cystitis or Bladder Pain Syndrome
Interstitial cystitis is a chronic condition involving bladder pressure or pain without a typical bacterial infection. Discomfort often becomes stronger as the bladder fills and temporarily improves after urination. People may also experience urinary urgency, frequent urination and pain during sex.
-
5. Irritable Bowel Syndrome
Irritable bowel syndrome, commonly called IBS, can cause lower abdominal or pelvic cramping, bloating and changes in bowel habits. Some people mainly experience constipation, while others have diarrhea or alternate between the two. The pain is frequently related to bowel movements and may ease after passing stool or gas.
-
6. Constipation or Fecal Impaction
Hard stool and a backed-up colon can create significant pressure in the lower abdomen and pelvis. Symptoms may include infrequent bowel movements, straining, bloating and the sensation that stool remains after using the bathroom. Constant pain, vomiting, fever, rectal bleeding or an inability to pass gas requires medical attention.
-
7. Diverticulitis or Colitis
Inflammation in the colon can be felt deep in the pelvis, particularly when the lower portion of the bowel is involved. Diverticulitis commonly causes persistent lower-left abdominal pain, fever and bowel changes. Colitis may produce cramping, diarrhea, urgency, mucus or blood in the stool. These symptoms should not be dismissed as an adventurous lunch fighting back.
-
8. Hernia
A hernia develops when tissue pushes through a weakened area of muscle. An inguinal or femoral hernia may cause groin or pelvic discomfort, especially while lifting, bending, coughing or standing. A visible or tender bulge may appear. Severe pain, vomiting or a bulge that becomes hard and cannot be pushed back can indicate trapped tissue and requires emergency care.
-
9. Pelvic Floor Dysfunction
The pelvic floor must contract and relax in a coordinated way. When its muscles remain too tight, become weak or spasm, a person may develop pelvic pressure, painful sex, constipation, urinary problems or pain in the rectum, vagina, penis or perineum. Treatment may include specialized pelvic floor physical therapy rather than automatically performing more strengthening exercises.
-
10. Muscle, Joint or Bone Problems
A strained abdominal muscle, irritated hip joint, pelvic injury or lower-back condition can refer pain into the pelvis. The discomfort may worsen with walking, climbing stairs, changing position or exercising. Pregnancy can also place extra stress on the pubic joint and surrounding ligaments. Musculoskeletal pain is often reproducible with certain movements or pressure.
-
11. Pudendal Neuralgia
Pudendal neuralgia occurs when a major pelvic nerve becomes irritated, compressed or damaged. It can cause burning, tingling, numbness or electric-shock-like pain around the anus, genitals and perineum. Sitting may make the pain considerably worse, while standing or lying down may help.
Pelvic Pain Causes Primarily Affecting Women
-
12. Menstrual Cramps
During menstruation, the uterus contracts to shed its lining. These contractions can cause lower abdominal cramping that spreads into the back or thighs. Mild-to-moderate cramps are common, but pain that prevents normal activities, appears later in life or becomes progressively worse may be related to an underlying condition.
-
13. Ovulation Pain
Some women feel one-sided pelvic pain when an ovary releases an egg. Known as mittelschmerz, this discomfort typically occurs around the middle of the menstrual cycle and may last from a few minutes to one or two days. It can feel dull and crampy or suddenly sharp, sometimes with light spotting.
-
14. Endometriosis
Endometriosis occurs when tissue similar to the uterine lining grows outside the uterus. Common symptoms include painful periods, pain during or after sex, discomfort with bowel movements or urination, heavy bleeding and difficulty becoming pregnant. The intensity of pain does not always reflect how extensive the condition is.
-
15. Adenomyosis
In adenomyosis, tissue from the uterine lining grows into the muscular wall of the uterus. This can make the uterus enlarged and tender. Symptoms may include heavy or prolonged periods, severe cramps, pelvic pressure and ongoing pain. The condition is particularly common among people in their later reproductive years.
-
16. Uterine Fibroids
Fibroids are noncancerous growths that develop in or around the uterus. Small fibroids may cause no symptoms, while larger ones can create pelvic pressure, heavy bleeding, frequent urination, constipation, back pain or a visibly enlarged lower abdomen. Their location can matter as much as their size.
-
17. Ovarian Cyst or Ruptured Cyst
Many ovarian cysts are harmless and disappear without treatment. A larger cyst may cause one-sided aching, pressure, bloating or pain during sex. When a cyst ruptures, the pain may become sudden and sharp. Severe pain accompanied by weakness, dizziness, vomiting or heavy bleeding may indicate significant internal bleeding.
-
18. Ovarian Torsion
Ovarian torsion happens when an ovary twists around its supporting tissues, reducing or stopping its blood supply. It usually causes sudden, severe, one-sided pelvic or lower abdominal pain, often with nausea and vomiting. This is a time-sensitive emergency requiring immediate hospital evaluation.
-
19. Pelvic Inflammatory Disease
Pelvic inflammatory disease, or PID, is an infection of the upper female reproductive organs. It is often associated with untreated chlamydia or gonorrhea, although other bacteria can be responsible. Possible symptoms include lower abdominal pain, unusual vaginal discharge, painful sex, bleeding between periods, painful urination and fever. Some cases produce only subtle symptoms.
-
20. Ectopic Pregnancy
An ectopic pregnancy develops outside the uterus, most commonly in a fallopian tube. Early symptoms may include a missed period, abnormal vaginal bleeding and pain on one side of the pelvis. Shoulder pain, fainting, severe weakness or rapidly worsening pain can indicate internal bleeding from a rupture and demands emergency treatment.
-
21. Pelvic Organ Prolapse or Pelvic Congestion
Pelvic organ prolapse occurs when weakened support tissues allow the uterus, bladder or rectum to descend toward the vagina. It may cause heaviness, pressure, urinary leakage or the feeling of a vaginal bulge. Pelvic congestion syndrome involves enlarged pelvic veins and can cause a dull ache that worsens after prolonged standing, during sex or near menstruation.
Pelvic Pain Causes Primarily Affecting Men
-
22. Prostatitis or Chronic Pelvic Pain Syndrome
Prostatitis refers to inflammation of the prostate, which may or may not be caused by bacteria. Pain can develop above the pubic bone, in the lower back, around the penis or testicles, or between the scrotum and anus. Other symptoms include urinary burning, difficulty starting the urine stream, urinary frequency and painful ejaculation.
-
23. Epididymitis or Orchitis
Epididymitis is inflammation of the coiled tube behind a testicle, while orchitis affects the testicle itself. Infection is a frequent cause. Symptoms can include gradually worsening testicular or groin pain, swelling, warmth, urinary burning, discharge or fever. The pain may spread upward into the lower abdomen or pelvis.
-
24. Testicular Torsion
Testicular torsion occurs when the spermatic cord twists and cuts off blood flow to a testicle. It typically causes sudden, intense pain on one side of the scrotum, sometimes accompanied by lower abdominal or pelvic pain, swelling, nausea and vomiting. Immediate emergency treatment is necessary to preserve the testicle.
Other Symptoms That May Accompany Pelvic Pain
The accompanying symptoms often reveal more than the pain location alone. A healthcare professional may ask whether the pain is associated with:
- Burning, urgency, difficulty or increased frequency during urination
- Blood in the urine or difficulty emptying the bladder
- Constipation, diarrhea, bloating or pain during bowel movements
- Rectal bleeding, black stool or mucus in the stool
- Abnormal vaginal bleeding or unusual vaginal discharge
- A missed period or positive pregnancy test
- Pain during or after sex
- Penile discharge, painful ejaculation or blood in semen
- Scrotal swelling or testicular pain
- Fever, chills, nausea, vomiting, dizziness or fainting
- Back, hip, groin or thigh pain
- Unexplained fatigue, appetite loss or weight loss
Keeping a symptom diary can help identify patterns. Record the location, duration and severity of pain, along with meals, bowel movements, urination, physical activity, sexual activity and menstrual-cycle timing. Your notes need not resemble a medical textbook. A clear description such as “sharp pain on the left after urinating” is much more useful than “my pelvis is being weird again.”
When Pelvic Pain Is an Emergency
Seek emergency medical care for sudden or severe pelvic pain, especially when it occurs with fainting, confusion, weakness, heavy bleeding, repeated vomiting, a rigid abdomen or difficulty breathing. Immediate assessment is also important for pelvic pain during pregnancy, sudden testicular pain or an inability to urinate.
Other warning signs include high fever, blood in the stool, severe pain after an injury, a painful nonreducible groin bulge and signs of shock such as pale skin, rapid breathing or a racing pulse. New pain that interrupts sleep, interferes with daily activities or steadily worsens should be evaluated even when it is not an emergency.
How Doctors Evaluate Pain in the Pelvis
Evaluation usually begins with a detailed discussion of the pain. The clinician may ask when it started, whether it is constant or intermittent, what makes it worse and whether it follows a menstrual, urinary, digestive or sexual pattern.
Depending on the symptoms, testing may include a physical examination, pelvic or rectal examination, pregnancy test, urinalysis, STI testing, blood work or stool testing. Ultrasound is frequently used to examine reproductive organs and the bladder. Computed tomography may be appropriate when appendicitis, kidney stones or bowel disease is suspected. MRI, cystoscopy, colonoscopy or laparoscopy may be considered in selected cases.
Treatment depends on the cause and may include antibiotics, hormonal medication, bowel management, pain-relieving medicine, pelvic floor physical therapy or surgery. Because chronic pelvic pain frequently has more than one contributor, successful care may involve gynecology, urology, gastroenterology, pain medicine and physical therapy.
Experiences With Pelvic Pain: What the Search for Answers Can Feel Like
The following are fictional composite experiences based on common symptom patterns. They do not describe specific patients and should not be used for self-diagnosis.
The Pain That Followed a Calendar
A woman in her early thirties notices that her lower abdominal pain appears several days before every period. At first, she assumes that everyone spends one weekend each month folded around a heating pad. Over time, the cramps become stronger, sex becomes uncomfortable and bowel movements during menstruation feel unusually painful.
Tracking the symptoms reveals a predictable monthly pattern. She brings the diary to a gynecology appointment, where the clinician discusses possible endometriosis and explains that severe menstrual pain should not automatically be considered normal. The important part of the experience is not the eventual diagnosis; it is recognizing that repeated disruption deserves investigation.
The “UTI” That Was Not a UTI
Another person develops bladder pressure, urinary urgency and pelvic aching. The symptoms certainly act like a UTI, but repeated urine cultures do not show an infection. Drinking more water helps only temporarily, and antibiotics do not solve the problem.
The discomfort is worse when the bladder is full and eases briefly after urination. That pattern prompts an evaluation for interstitial cystitis and pelvic floor muscle tension. The experience illustrates why repeating the same treatment without confirming the cause can lead to months of frustration. Similar symptoms do not always come from similar conditions.
The Desk Job and the Burning Seat
A man working long hours at a computer develops burning pain between the scrotum and anus. Sitting through a meeting becomes miserable, but standing or walking provides some relief. He also notices urinary hesitation and occasional discomfort after ejaculation.
He initially worries about prostate cancer. His clinician finds no evidence of cancer but evaluates him for chronic prostatitis or chronic pelvic pain syndrome, along with pelvic floor dysfunction. Physical therapy, activity changes and coordinated medical treatment gradually reduce the symptoms. The process reinforces an important point: pelvic pain can involve muscles and nerves even when no dramatic abnormality appears on a scan.
The Sudden Pain That Could Not Wait
A teenager wakes with intense pain in one testicle, nausea and lower abdominal discomfort. He feels embarrassed and considers waiting for it to pass. Fortunately, a family member recognizes that sudden testicular pain is not a “see how it feels tomorrow” situation and takes him to an emergency department.
Doctors rapidly evaluate him for testicular torsion. This experience represents the opposite of chronic pelvic pain: the timing is abrupt, the pain is severe and every hour matters. Embarrassment should never delay emergency care for sudden genital, groin or pelvic pain.
What These Experiences Have in Common
Pelvic pain can be difficult to discuss because it involves private bodily functions, sexual symptoms or areas people would rather not mention over lunch. Yet accurate details help clinicians narrow the possibilities. Describing discharge, bleeding, painful sex, urinary changes or bowel problems is medically usefulnot oversharing.
People may also need more than one appointment before the full picture becomes clear. Chronic pelvic pain can shift over time and involve several systems simultaneously. Asking what diagnoses have been ruled out, what warning signs require urgent care and what the next diagnostic step will be can make the process feel less mysterious.
Conclusion
Pain in the pelvis can originate from the bladder, bowel, reproductive organs, prostate, muscles, joints or nerves. Some causes are temporary and manageable, while others require urgent treatment. The most helpful clues include how suddenly the pain began, its precise location, its relationship to urination or bowel movements and whether it occurs with bleeding, fever, vomiting, pregnancy or genital swelling.
Do not ignore new pelvic pain that persists, repeatedly returns or interferes with normal life. A careful medical evaluation can identify treatable conditions, prevent complications andequally importantreplace internet-fueled guesswork with a practical plan.
