Well, last night I noticed a painful knobby bump under the skin around the opening down there, and its been bothering me quite a lot.
For the past year or so, whenever I make a 'bowel movement,' that doesn't have much fiber in it, I sometimes get a really bad sharp pain inside my anus... but it usually goes away after a few seconds. I'm not sure if that is related to the bump.
It may be a hemorroid, but I'm only 15 years old and I'm male... which seems rather odd to me.
