So last year around christmas I had a root canal done. And afterwards they gave me some antibiotics to take. And i started taking them, then next thing I know like a week later I break out in this itchy red rash ONLY across my chest. It was only in that area and it became red and itched constantly & also gets very hot like i could feel that area on my body is more hot than anywhere else. And then i look up the antibiotics they gave me and then BINGO! the side effects is "causes itchy red rash" And i thought omg thats it. So i stop taking them. And then with some creams it eventually went away. But now even though I haven't taken those pills since i continuously keep having the rash reoccur in the same spot. It goes away for 3 or 4 months then returns again. And I've never gotten any itchy rashes in my life till these pills from the dentist. Why wont it stop even though I stopped taking the pills long time ago? Please help!
