I had a group of small red bumps on my left butt cheek about an inch or two to the left of the rectal are and I had a small patch in between my left thumb and finger. They did not itch and did not hurt except after a few days rubbing on my jeans. I noticed the one on my thumb area had a few little spots that looked like some fluid might be in it but it did not drain or anything. I did not feel drainage on the butt area. I put antibiotic ointment on them and the one on my hand is almost gone and the one on the butt cheek is almost gone but I was worried because it looks dark red, almost purple. What could it be?tay
