Same thing happened to me. I was given antibotics to clear up the infection. The dr said it was Staph. She said after it was cleared up, I would have to go to a plastic surgeon to have the lump/knot removed/cut out.
The antibotics made the size of the lump almost un- noticable so I put off further treatment . This occurred around July, now it is Sept 2010 and the knot is getting bigger again and is getting sore. So i made a app with a dermatologist
and will prob have to do to a plastic surgeon afterwards. My skin has never been the same since the lump. Alieame1234@yahoo.com
