Hey, I'm still waiting for a diagnosis lost over 50 pounds at this point. Anyway, I have two spots near my anus that are purple and look like blood blisters. They are about the size of the tip of my pinky, maybe a bit smaller then that. I noticed them because them were soar and I wanted to see what was going on considering everything else. I know they are not an STD because I have only been with my girlfriend. Can anyone tell me if these are normal. They don't stick out and they don't look like a hemroid.
