Ok this is really weird as I was starting to freak out thinking that I was a freak or something with this problem. Im also 16 and have found a smal lump on my anus. It suddenly appeared a few days ago, I didn't notice it until I went to the toilet and was in immense pain. It is making it very painful for me to sit down, but when I do manage to sit down for a while I am unable to move. I'm usually very active and at the present time I am unable to do any sports or walk at all.
It is pink in colour, the same as the skin surrounding it and is the shape of a chocolate minstrel which looked like it is stuck in there.
I'm starting to get really worried now as I am too embassed to tell anybody even my parents. Does anybody have an idea about what it could be?
