Question: Towards the middle of XXXXXXX 2011, I was injured behind my scrotum by the crease of my leg (but enough where I think I hit my perinium). I felt sharper pain and decided to "walk it off" and it went away...or so I thought! The next morning, I woke up and screamed in pain. I took a look down there and saw that my entire scrotum and penis was bruised. I decided to apply ice. It went away again. I noticed about 2 weeks llater that the same spot was starting to hurt when I walked a certain way or sat down too much (sitting in traffic was murder!). I went down to the bathroom and saw that once again I was bruised in the same area. By the time I walked to the fridge, bruise was gone (both cases like a dark purple color) and the pain went away. I took it as a muscle bruise and decided to walk a bit slower and decided to wear slightly tighter underwear so everything wouldn't "swing around" free and cause more pain. Occassionally, I also felt tingling sensations behind my scrotum (exactly where that folding of the skin is and I would become erect for no reason and then the sensation would subside.

Last week, I felt the burning pain from my scrotum head all the way down to the side of my anus. Since then, I feel like I've gotten IBS and also lost some sensation in the anus. I say I think I had IBS because I've got a long history of stomach problems and have had similar symptoms briefly but I've had the cramping, bloating, etc for a full day. At first I didn't know what it was, and then I remembered the same symptoms so I began doing the BRAT diet for the remainder of the day and into yesterday. I able able to excrete waste and I do feel my muscles contracting when I push. But, I've lost that tightness where someone would be like "Uh oh, I better find a bathroom quick!" At times, I cannot feel my bowels emptying. It feels like the waste has "slipped through" even when I am "pushing" at a fair amount of pressure. Also, when I wipe my anus I barely feel the paper. One time, I bled from wiping myself too hard from a brief case of diarrea from stomach flu and the only time I felt the paper was when I applied it to the scraped area where bleeding had occurred. I should mention that I did go to a urologist and my GP while all this was occurring. The urologist said I was "fine" and "everything seems normal" after doing a visual and manual exam. I questioned him about testicular torsion and he completely ruled it out. He then fed me a line how "the scrotum can take a bullet" and how my pain is "nothing to worry about" - that was in July, just about 2 weeks after the incident. (This is the 2nd day of the new year and I totally beg to differ with him!). As I said, I saw my GP and basically he said to see my GI doctor when stomach pain occurs. The reason I'm questioning my stomach pain is, again, I've got a history of GI issues (GERD, Lactose Intolerance, and so on). I'm really wondering if this IBS-like episode is related to the pain down there or is it because of my eating habits and they just happen to be working "side by side" yet they haven't really "connected" since one existed before the other did. HELP!!!

The injury did not occur at the anal sphincter directly. It was at the "flap" of skin behind the scrotum. From there, the pain streaked downwards. This afternoon, I decided to eat salad in order to promote excretion. Hours later, I had diarrea unlike other times where I literally had to force myself to excrete or excrete "ribbon-like" feces.
By the way, I have noticed that i get these nerves on the back of my shoulders twitching This usually runs down both sides of my back down to my lower back.
Could pudendal nerve entrapment be ruled out too?
