Genital pain has dozens of possible causes, ranging from a simple skin irritation that clears up in a day to infections that need treatment. The cause often depends on exactly where the pain is, what it feels like (burning, aching, sharp, or throbbing), and whether other symptoms came along with it. Here’s a practical walkthrough of the most common reasons, what to look for, and what typically helps.
Infections That Cause Burning or Aching
Urinary tract infections are one of the most common culprits behind genital pain, especially a stinging or burning sensation when you pee. You may also feel pressure or discomfort low in your abdomen, need to urinate more often than usual, or notice that your urine looks cloudy. UTIs are far more common in people with vaginas because of shorter urinary anatomy, but they can affect anyone. If the infection spreads upward toward the kidneys, you may develop lower back pain on one or both sides along with a fever.
Yeast infections produce a different kind of discomfort: itching, burning, and soreness around the vulva or inside the vagina, often with thick, white, odorless discharge. Bacterial vaginosis, by contrast, tends to cause less intense irritation but comes with grayish, foamy discharge that smells fishy. Both are extremely common and not sexually transmitted, though sex can shift the balance of bacteria or yeast that triggers them.
Sexually Transmitted Infections
Several STIs cause genital pain, and their timelines can help you connect symptoms to a recent exposure. Chlamydia symptoms typically start 5 to 14 days after exposure and can include painful urination, lower abdominal pain, vaginal pain during sex, or testicle pain and swelling. Gonorrhea follows a similar pattern, often appearing within 5 days in people with penises and within 10 days in people with vaginas. Both infections can also cause rectal pain if transmitted through anal sex.
Genital herpes tends to show up within about 12 days of exposure. The pain often starts as itching or tingling in the genital area, buttocks, or inner thighs, then progresses to small sores or ulcers that can make urination painful. The tenderness usually lasts until the outbreak clears. Trichomoniasis, a parasitic infection, can appear anywhere from 5 to 28 days after exposure and causes vaginal burning, soreness, irritation, or pain during sex. In people with penises, it may cause itching or irritation inside the urethra.
Syphilis is the exception to the “pain” pattern. Its first sign is usually a small, painless, firm sore wherever the bacteria entered the body. Because it doesn’t hurt, it’s easy to miss entirely.
Skin Irritation and Contact Reactions
Sometimes the pain isn’t from an infection at all. Genital skin is thinner and more sensitive than skin elsewhere on your body, which makes it highly reactive to everyday products. Common triggers include soap, bubble bath, scented laundry detergent, dryer sheets, synthetic underwear (especially nylon), scented pads or panty liners, douches, deodorant sprays, spermicides, and even certain toilet papers or dyes.
This type of irritation, called contact dermatitis, typically causes redness, itching, burning, or a raw feeling on the vulva, penis, or surrounding skin. It often improves within a few days once you remove the irritant. Switching to fragrance-free products, wearing cotton underwear, and washing the area with plain warm water instead of soap can make a noticeable difference.
Pelvic Inflammatory Disease
Pelvic inflammatory disease (PID) develops when bacteria, often from an untreated chlamydia or gonorrhea infection, spread from the vagina into the uterus, fallopian tubes, or ovaries. Symptoms include lower abdominal pain, fever, unusual foul-smelling discharge, pain or bleeding during sex, burning when you urinate, and bleeding between periods. Some people have symptoms so mild they don’t realize anything is wrong.
PID matters because delaying treatment raises the risk of serious complications: scar tissue that blocks the fallopian tubes, ectopic pregnancy, infertility, and chronic pelvic pain that can persist long after the infection itself is gone. The longer treatment is delayed, the more likely these complications become.
Conditions That Affect the Testicles
Epididymitis is inflammation of the coiled tube behind each testicle. It causes scrotal pain that may spread into the groin, along with swelling, and sometimes fever, chills, or pain when urinating. The pain can be on one side or both and ranges from mild to severe. In younger, sexually active people it’s often caused by chlamydia or gonorrhea. In older adults, it more commonly results from a urinary tract infection or prostate infection that spreads.
Testicular torsion is a true emergency. It happens when a testicle twists on its cord, cutting off blood flow. The hallmark is sudden, severe scrotal pain, often with nausea, vomiting, abdominal pain, and swelling. The affected testicle may sit higher than usual or at an odd angle. Without treatment within several hours, the testicle can be permanently damaged and may need to be surgically removed. If you experience sudden, intense testicle pain, get emergency care immediately.
Chronic Vulvar Pain (Vulvodynia)
Some people with vulvas experience persistent pain lasting three months or longer with no identifiable infection, skin condition, or injury. This is called vulvodynia. The pain can be localized to the vaginal opening (vestibulodynia) or spread across the entire vulvar area. It may be triggered by touch, pressure, or penetration, or it may be constant without any obvious trigger.
Vulvodynia is real, it’s not “in your head,” and it has effective treatments. Pelvic floor physical therapy is one of the most commonly recommended approaches, using techniques like soft-tissue work, biofeedback, and therapeutic exercises to retrain the muscles and nerves in the area. Nerve stimulation therapy has also shown improvements in both pain and sexual function in clinical trials. For pain localized to the vestibule that hasn’t responded to other treatments, a minor surgical procedure called a vestibulectomy has success rates between 60% and 90%.
How to Find Relief at Home
While you’re figuring out what’s going on, a sitz bath can help ease soreness, itching, and general discomfort. Fill a bathtub or basin with a few inches of warm water, around 104°F (40°C), and soak the area for 15 to 20 minutes. You can do this up to three or four times a day. Use plain water with nothing added unless specifically instructed otherwise.
Other steps that help across many causes: avoid scented products in the genital area, wear loose-fitting cotton underwear, don’t douche, and urinate after sex to help flush bacteria from the urethra. If your pain came on suddenly, is severe, involves fever, or hasn’t improved after a few days of home care, those are signs that something beyond simple irritation is going on and that getting evaluated sooner will lead to a better outcome.
