My son is 2.5 years old and he has always complained that his bum hurts. This weekend I noticed that it was really bad so much that he could not sit right. He was leaning to the side. So, while changing him I had him push a little like he was taking a poop and I saw something red to one of the sides on the inside of his bum. It was red and glossy. Sorry to be so detailed but I am wondering if its just a hemrrhoid.
