I went to the doctor about two months ago and was diagnoised with Molluscums. I have one on my thigh that recently just got swollen, red and purple, and is painful like two days ago. The molluscum has been there the whole time it just started doing this. Also I do not shave or put anything on it because the doc told me to leave it alone. Does this mean the molluscum us about to pop? Or is it more serious? Also I noticed there is like a very small black dot on it. Almost like a black head.
