I had my birthmark on my left cheek treated. It was a topical, non surgical procedure. A medicine is applied which hardens the area, a kind of a clot forms which peels the birthmark along with it when it dries and comes off.The birthmark has almost come off, but a pus has developed underneath the clot kind of thing. My face pains and I have been feeling feverish for the last few days. I am worried because I read somewhere that pus, if not treated might spread to other areas internally like eyes or brain and I then might have to get a brain surgery to remove it??? Please help!!!
