Hi . Sorry you are experiencing this pain. Has your doctor had any feedback on this postoperative symptom? I can't personally speak to this issue, but I can tell you that perineal pain (the area between the scrotum and the rectum) is not uncommon. In addition, there is often rectal pressure from bloating which can cause pain and many notice rectal pain when sitting (don't know if this is when you are experiencing it). Of course, only a doctor can provide the proper diagnostics. Hopefully others will chime in with their experiences. Hope you get some answers and relief soon. Best, Richard (ProstateCancer.net Team)
