Pelvic pain has dozens of possible causes, ranging from temporary muscle strain to conditions that need treatment. About 1 in 7 women in the United States experience chronic pelvic pain, and 2% to 16% of men deal with it too. The challenge is that your pelvis houses your bladder, intestines, reproductive organs, muscles, and nerves, so pain in this area rarely points to one obvious source without some investigation.
Reproductive Organ Causes in Women
For women, the most common pelvic pain culprits involve the uterus or ovaries. Endometriosis, where tissue similar to the uterine lining grows outside the uterus, causes deep, often cyclical pain that can radiate through the pelvis and lower back. It’s notoriously underdiagnosed: the average time from first symptoms to confirmed diagnosis ranges from 5 to 12 years globally, though recent U.S. data suggest that gap may be narrowing to around 4.4 years. If your pelvic pain consistently worsens around your period, endometriosis is worth raising with your doctor.
Ovarian cysts are another frequent source. Most are harmless fluid-filled sacs that form during ovulation and resolve on their own. They only tend to cause significant pain when they rupture or bleed internally, which can feel like a sudden, sharp stab on one side. Ovarian torsion, where the ovary twists on its blood supply, produces severe one-sided pain and is a medical emergency.
Pelvic inflammatory disease (PID), an infection of the reproductive tract usually caused by sexually transmitted bacteria, brings pelvic pain along with unusual discharge, fever, or pain during sex. Uterine fibroids, which are noncancerous growths in the uterine wall, can create a dull heaviness or pressure in the lower pelvis, especially as they grow larger.
Common Causes in Men
When men experience pelvic pain, the prostate gland is often the first suspect. Bacterial prostatitis causes sudden pain, burning with urination, and sometimes fever. But only 5% to 10% of prostatitis cases actually involve a bacterial infection. The rest fall under what’s called chronic pelvic pain syndrome, a condition where pain persists for three months or longer without a detectable infection. It can involve urinary urgency, discomfort during or after ejaculation, and pain that settles between the scrotum and rectum.
An estimated 2% to 10% of men experience prostatitis-like symptoms at some point. The pain is often accompanied by anxiety or depression, which can amplify the sensation of pain and create a frustrating cycle. Other urological causes to rule out include urethritis (inflammation of the tube that carries urine), benign prostate enlargement in older men, and, less commonly, bladder conditions.
Bladder and Digestive Causes
Several non-reproductive organs in the pelvis can generate pain that feels identical to a gynecological or prostate problem. Urinary tract infections cause burning, urgency, and a pressure-like ache in the lower pelvis that clears with antibiotics. Interstitial cystitis, sometimes called painful bladder syndrome, produces similar symptoms but without an infection. The bladder wall becomes chronically irritated, leading to pelvic pressure that worsens as the bladder fills and eases temporarily after urination.
Irritable bowel syndrome (IBS) frequently overlaps with pelvic pain. Cramping, bloating, and altered bowel habits can create lower abdominal and pelvic discomfort that shifts throughout the day. Constipation alone can cause enough pressure in the pelvis to mimic other conditions. Inflammatory bowel disease, diverticulitis, and even chronic appendicitis are less common but worth considering if digestive symptoms accompany your pain.
Pelvic Floor Muscle Problems
Your pelvic floor is a hammock of muscles stretching across the bottom of your pelvis, supporting your bladder, bowel, and reproductive organs. When these muscles stay chronically tight instead of relaxing normally, they can produce ongoing pain in the pelvic region, genitals, or rectum. This is pelvic floor dysfunction, and it’s one of the most overlooked causes of pelvic pain in both men and women.
The pain can show up with or without bowel movements, during sex, or simply while sitting. In men, pelvic floor tension can contribute to erectile difficulties, though the relationship is complex. People with pelvic floor dysfunction often tighten these muscles unconsciously, especially during stress, which gradually worsens the problem. Physical therapy focused on the pelvic floor is one of the most effective treatments. It goes beyond stretches and relaxation techniques to include hands-on work that addresses specific trigger points. When physical therapy alone isn’t enough, targeted injections of numbing medication into overly tense muscles can help break the cycle.
Nerve-Related Pelvic Pain
The pudendal nerve runs through the pelvis and supplies sensation to the genitals, perineum (the area between your genitals and anus), and rectum. When this nerve gets compressed or irritated, it produces burning or aching pain that worsens with sitting and improves when you stand or lie down. That sitting-specific pattern is the hallmark symptom, reported by more than half of people with the condition.
Pudendal nerve problems can develop from prolonged sitting, cycling, pelvic surgery, childbirth, or pelvic fractures. The nerve can become pinched between ligaments deep in the pelvis or within a narrow canal alongside one of the hip muscles. Beyond pain, it can cause urinary urgency, constipation, sexual dysfunction, or a strange foreign-body sensation in the rectum or vagina. Because the symptoms overlap with so many other pelvic conditions, pudendal neuralgia often takes a long time to identify.
How Pelvic Pain Gets Diagnosed
Ultrasound, both through the abdomen and vaginally, is the first imaging tool used to evaluate pelvic pain. It’s fast, widely available, and effective at identifying ovarian cysts, fibroids, ovarian torsion, and signs of ectopic pregnancy. Ovarian cysts show up as thin-walled sacs, while a twisted ovary appears enlarged with displaced follicles and disrupted blood flow on Doppler imaging.
CT scans offer a broader view when ultrasound doesn’t provide a clear answer, but MRI is preferred for younger patients and anyone who is pregnant because it avoids radiation. MRI is also better at detecting deep pelvic endometriosis and provides more detail for complex cases. For men, urine cultures and prostate exams help distinguish between bacterial infections and chronic pain syndromes. A structured evaluation matters because many pelvic pain conditions share overlapping symptoms, and more than one problem can be present at the same time.
Managing Pelvic Pain
Treatment depends entirely on the cause, but several approaches help across multiple pelvic pain conditions. Pelvic floor physical therapy benefits people with muscle-related pain, nerve irritation, and even pain from endometriosis or interstitial cystitis, because chronic pelvic pain of any origin tends to create secondary muscle tension. Heat applied to the lower abdomen or pelvis can ease cramping and muscle tightness in the short term.
For chronic pelvic pain that has persisted for months, treatment often works best as a combination. Physical therapy, medication for the underlying condition, and psychological support together tend to produce better results than any single approach. Depression and anxiety commonly develop alongside chronic pelvic pain, and addressing them directly through therapy can reduce pain perception and improve daily functioning. This isn’t because the pain is “in your head.” Chronic pain physically changes how your nervous system processes signals, and talk therapy helps reverse some of those changes.
If your pelvic pain is new and came on suddenly with fever, heavy bleeding, dizziness, or severe one-sided pain, those patterns suggest conditions like ectopic pregnancy, ovarian torsion, or pelvic infection that need prompt evaluation. Pain that has been building gradually over weeks or months is less likely to be an emergency but still deserves a thorough workup, especially if it’s interfering with sleep, sex, exercise, or your ability to sit comfortably.
