Hi, my name is Michelle. I havea 28 yrold son who is a heroin abuser, has been for awhile. Yesterday he woke up to a goose egg bump on his forehead that was painful. Has not had any injury. Doctor didn't know what it was, gav him antibitics and ibuporphen. Today the whole left side of his face is more swollen, painful and his eye is nearly shut. Any idea whats going on?
