What might be causing simultaneous pain in the scrotum and anus?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Pain in the scrotum and anus is often caused by infections (such as urinary tract or sexually transmitted infections), nerve-related conditions like pudendal neuralgia, or referred pain from lower back issues, including lumbar disc degeneration. Pelvic floor dysfunction and prostatitis are also common contributors in men.

Because these causes range from easily treatable infections to nerve or spine conditions that need targeted care, guessing can delay relief and lead to complications. The fastest way to narrow things down is to review your specific symptoms against known conditions. Take a free, instant, online symptom check to better understand what may be causing your pain and get clear guidance on your next steps.

Explanation

Pain in both the scrotum and anus at the same time can be uncomfortable and concerning. This pain might be linked to nerve problems. The pudendal nerve plays a crucial role in the pelvic area, and issues with it can cause pain in the perineal region, which includes the scrotum and anus. If this nerve is irritated or compressed, it can lead to discomfort in these areas.

Another possible cause is lumbar disc degeneration. This condition affects the discs in the lower back, and when these discs wear down, they can press on nerves that lead to pain in areas like the scrotum and anus.

Another common cause can be a rectal/pelvic or abdominal infection which can cause referred pain. This needs to be addressed urgently with a healthcare provider.

Understanding the exact cause of the pain requires careful evaluation by a healthcare professional. They might look at nerve-related issues or examine the lower back to find the source of the pain. If you are experiencing such symptoms, you can start by using a free symptom checker to help identify possible causes before reaching out to a healthcare provider for proper assessment and guidance.
