Hi. I just sat down today in a certain position, and I felt a sharp pain on my right buttock. I then noticed that there is a small lump on the inner part of my right buttock. It is not really visible by the eye, but if I put my finger on it, I can feel some sort of lump inside my skin. I actually have been feeling like there is something in my butt for the past about 2 to 3 weeks. However, just this week, I started feeling some pain when I wipe that area of my buttock after going to the bathroom. Just today I noticed the lump though when I felt it with my finger. I'm not sure as to when the lump exactly developed. Do you know what this could be? Also, what type of doctor am I supposed to see about this?
