Pain in the pelvic or genital area has dozens of possible causes, ranging from a simple urinary tract infection to tight pelvic floor muscles to conditions like endometriosis. The cause depends on where exactly the pain is, how long it’s lasted, and what other symptoms come with it. Roughly 15% of adults in the United States experience chronic pelvic pain at some point, so this is far from rare.
Because “down there” can mean different things to different people, this guide covers the most common reasons for pain in and around the genitals, pelvis, and lower abdomen for both women and men.
Urinary Tract Infections
A UTI is one of the most frequent reasons for sudden burning or pressure down below. The hallmark symptom is a burning sensation when you urinate, along with a persistent urge to go even when very little comes out. You might also notice urine that looks pink, red, or dark brown, which can signal blood. When the infection is in the bladder, it often produces pelvic pressure and lower belly discomfort. When it’s limited to the urethra, burning and sometimes discharge are the main complaints.
UTIs are far more common in women than men due to a shorter urethra, but they can affect anyone. They’re typically caused by bacteria and clear up with a short course of antibiotics. Left untreated, a bladder infection can travel to the kidneys, which causes flank pain, fever, and nausea.
Vaginal Infections
Two of the most common vaginal infections, yeast infections and bacterial vaginosis (BV), both cause discomfort in the vulva and vagina but look quite different. A yeast infection typically produces thick, white, odorless discharge along with intense itching and sometimes a white coating in and around the vagina. BV, on the other hand, tends to cause grayish, foamy discharge with a noticeable fishy smell, though many people with BV have no symptoms at all.
Both conditions cause irritation, swelling, and burning in the vulva or vagina. Yeast infections are caused by fungal overgrowth and can be treated with antifungal medication. BV involves an imbalance of normal vaginal bacteria and requires a different type of treatment. Because the symptoms overlap, it’s worth getting the right diagnosis rather than guessing.
Menstrual Cramps and Ovulation Pain
For many women, the most familiar pelvic pain is simply menstrual cramping. The uterus contracts to shed its lining, and those contractions can radiate through the lower abdomen, back, and upper thighs. Cramps that consistently disrupt your daily life or get worse over time may signal something beyond a normal period.
Some women also feel a sharp, one-sided twinge mid-cycle when an ovary releases an egg. This is sometimes called ovulation pain. It’s usually brief, lasting minutes to a day, and alternates sides from month to month.
Endometriosis
Endometriosis occurs when tissue similar to the uterine lining grows outside the uterus, on surfaces like the ovaries, fallopian tubes, or pelvic walls. This misplaced tissue still responds to hormonal cycles, causing inflammation and pain that can be severe.
The pain from endometriosis isn’t just simple cramping. The condition triggers an inflammatory cascade where immune cells release chemicals that directly activate and sensitize pain-sensing nerve fibers. Over time, new nerve fibers actually grow into and around the lesions, a process that amplifies pain signals. The nervous system itself can become rewired: peripheral nerves grow hypersensitive, and even the way the brain processes pain changes. This is why endometriosis pain often worsens over years and can eventually become constant rather than only showing up during a period.
Symptoms include painful periods, pain during or after sex, pain with bowel movements or urination, and sometimes heavy bleeding. Diagnosis often takes years because the symptoms overlap with so many other conditions.
Pelvic Floor Dysfunction
Your pelvic floor is a group of muscles that stretches like a hammock across the bottom of your pelvis, supporting the bladder, uterus or prostate, and rectum. Normally these muscles tighten and relax on command, much like clenching and releasing a fist. In pelvic floor dysfunction, the muscles stay chronically tight instead of relaxing. This constant tension causes ongoing pain in the pelvic region, genitals, or rectum.
For women, hypertonic (overly tight) pelvic floor muscles can make intercourse painful or even impossible, and make tampon use uncomfortable. The dysfunction can also cause trouble with bowel movements, a feeling of incomplete emptying, or urinary leakage. It frequently coexists with bladder pain conditions, creating a cycle where bladder irritation triggers muscle tightening, which increases pain, which makes the muscles tighten further.
Pelvic floor physical therapy is one of the primary treatments. A specialized therapist evaluates how the muscles, nerves, joints, and connective tissue are working together, then uses manual techniques to release trigger points and restore normal movement patterns. Learning to fully relax the pelvic floor through breathing exercises is a key part of recovery, especially for people with vulvar pain conditions.
Vulvodynia
Vulvodynia is chronic pain around the opening of the vagina that lasts longer than three months without an identifiable infection or skin condition to explain it. The pain can be localized to the vulva and perineum or spread to the lower abdomen, hips, buttocks, and rectum. Touch, tight clothing, sitting for long periods, and intercourse can all trigger or worsen it.
The underlying problem appears to involve nerve fibers that have become hypersensitive. They begin sending pain signals in response to stimulation that wouldn’t normally hurt, like light pressure or gentle touch. Over time, the central nervous system itself can become sensitized, making the pain more complex and harder to treat. Treatment typically combines pelvic floor therapy, nervous system calming techniques like breathing exercises and stress management, topical medications, and sometimes oral medications. Regular walking helps because it promotes the release of the body’s natural pain-relieving hormones.
Sexually Transmitted Infections and PID
Certain sexually transmitted infections, particularly chlamydia and gonorrhea, can cause pelvic pain directly or by leading to a more serious complication called pelvic inflammatory disease. PID is an infection of the reproductive organs that develops when bacteria from an STI spread upward from the cervix into the uterus, fallopian tubes, or ovaries.
PID can cause deep pelvic pain, pain during sex, unusual discharge, and sometimes fever. It’s a significant concern because untreated PID can lead to scarring of the fallopian tubes, chronic pain, and fertility problems. Many STIs cause few or no symptoms in their early stages, so pelvic pain that develops after unprotected sexual contact warrants testing even if no other symptoms are obvious.
Common Causes in Men
For men, the most common urologic diagnosis under age 50 is prostatitis, or inflammation of the prostate, which causes pain in the pelvis, groin, or genitals. Despite the name, most cases aren’t caused by a bacterial infection. The most frequently seen form involves chronic pelvic pain without any bacteria found in urine or prostate fluid. Risk factors include pelvic floor muscle tightness, urinary issues, diabetes, and prior catheterization, but in many cases there’s no clear trigger.
Bacterial forms of prostatitis can come on suddenly with fever and severe pelvic pain, or develop gradually with recurring, lower-grade discomfort. Testicular pain can also stem from other causes like epididymitis (inflammation of the tube behind the testicle, often from infection), inguinal hernias, or, less commonly, testicular torsion, which is a medical emergency involving a twisted testicle that cuts off its blood supply.
Digestive Causes That Mimic Pelvic Pain
Because the digestive tract runs through the pelvis, gut problems frequently masquerade as genital or reproductive pain. Chronic constipation creates pressure and discomfort in the lower abdomen that can feel like it’s coming from the bladder or uterus. Irritable bowel syndrome causes cramping, bloating, and pain that often concentrates in the lower belly. Appendicitis, which starts as a vague pain near the navel and migrates to the lower right side, is a classic mimic of ovarian or pelvic pain.
If your pain comes with changes in bowel habits, bloating, or nausea rather than urinary or sexual symptoms, a digestive cause is worth considering.
When Pain Needs Urgent Attention
Most pelvic pain isn’t an emergency, but some combinations of symptoms require immediate care. Sharp, sudden pelvic pain accompanied by excessive vaginal bleeding, fever, nausea or vomiting, or signs of shock like fainting signals a potentially dangerous condition. Ectopic pregnancy, ovarian torsion, and severe infections can all present this way. Sudden, intense testicular pain in men also requires emergency evaluation to rule out torsion, where time matters for saving the testicle.
Pain that has been building gradually over weeks or months is less likely to be an emergency but still deserves medical evaluation, especially if it’s affecting your sleep, daily activities, or sexual life. Chronic pelvic pain lasting longer than three months often involves changes in how the nervous system processes pain signals, which means earlier treatment tends to produce better outcomes than waiting it out.
