Lump under arm-staph?

I had a very tender lump about the size of a golf ball removed from my under arm in Oct. The doctor said it was a type of staph bacteria that I probably got from a razor that travelled down a hair shaft into my underarm. Now I have another one and its about the size of the end of my pinkie. I am taking the anitbiotics he gave me from the last time along with vitamin e 3x a day, echinacia 3x a day, l-lysine 2 pills 3x a day, red clover 3x a day. Is there anything else I can do to keep from having to go through surgery again?
