Cellulitis and abscess of trunk diagnosis. will this go away on it's own? er dr. said it needs to be removed, my surgeon says otherwise. dim. 3.7x2.6

Abscess: They may both be right, it is just a matter of timing. Usually infection on the skin starts as a red area called cellulitis an progresses to an abscess sometimes which is a pus collection. You may also have an infected sebaceous cyst and in some instances it is best to cool off with antibiotics and removed later unless an abscess is formed.
