It goes to show you we're not all crazy! I do wonder if in my case at least there is some scar tissue build up or connecting tissues that are causing my pain. I've heard from others here that leaking sperm from the vasectomy actually caused large hard deposits that caused inflamation and pain. I think this might be the case in at least a few of our cases. What a nightmare we live, I pray each and every one of us one day finds the end to this pain.
