Today in the shower I was cleaning off and I noticed a small lump about 1/2 inch into my anus while it is tightened. I cannot see the lump because it is 1/2 inch into my anus! It is painful to touch, seems to have appeared overnight, and is about the size of a pea. Not too much discomfort, but it itched severely for about 5 minutes later in the day(I did not scratch it). I had a BM and I felt no discomfort and no bleeding. What can this be??
Thank you guys
