I have a small 3-4 mm ball right under my skin in the jaw. I noticed it today, when I shaved, after 6-7 days. What is it and how do I get rid of it? Is there something to be worried about, in terms of malignant growth? It wasn t there last week for sure. A pharmacist looked at it and said it looked more like a rash, cos it was slightly reddish pink on the outside, cos of my constant touches. But I can feel it being on the inside of the skin. It s not a puss filled boil either. Just a hard ball, which hurts slightly when pushed in. Pls Help.
