I am a 19 year old male, and I have had a small hard bump on my right but cheek towards the top of the posterior. It started about 6 months ago as a flesh toned hard lump, but just recently it became about an inch wide of redness, lumpy, larger, and very painful. The soliditary feel of it extends past the redness about another half inch all around the redness. What am I experiencing, and how can I get rid of it!?
