Internal Medicine

Slight pain between the testicles and anus when sitting is often caused by pelvic floor muscle tension, nerve irritation (such as pudendal neuralgia), or inflammation in the perineum. Other possible causes include prostatitis, a perineal cyst, or minor trauma from prolonged sitting or cycling.

Because these symptoms can stem from several different conditions—some minor, some requiring medical attention—it's important to identify the likely cause before deciding on next steps. A free, instant, online symptom check can help you narrow down possible conditions based on your specific symptoms, so you can better understand what's going on and know whether self-care, a primary care visit, or a specialist consultation is the right move.

Explanation

Pain in the area between the testicles and anus, known as the perineum, can have several causes. One possibility is a problem with the muscles in this area.

Another possible cause could be nerve-related issues. Nerves in the pelvic area can sometimes become irritated or compressed, leading to discomfort when sitting.

Lastly, there could be an unusual swelling in the perineum, which might cause pain. Swelling can happen for different reasons, such as infection and needs to be checked by a healthcare professional immediately to understand the exact cause.

If the pain continues, you should talk to a healthcare provider who can look into these possibilities and provide advice on what to do next. To help identify what might be causing your symptoms, try Ubie's free AI symptom checker to get personalized insights in just a few minutes.
