I have been dealing with a very annoying, and uncomfortable, boil on my chest area. A few people had told me to put a onion, wrapped in gauze on it, my doctor tried to lantz it, that didn't work. She put me on some antibiobic, it had helped some, but... it is still there and just so annoying. I have never had anything like this in my life, what causes them? I have been taking supplements etc, but I always have. Can you give me some idea how to get rid of it! And how to prevent it coming back.
