I previously had MRSA under both arms.  I was treated with 2 types of antibiotics, but the knots never came to a head.  I went to a surgeon, but he did not intervene as head never formed.  It feels like I am getting the knots again in the same place.  Is this possible?  Does MRSA stay in the skin?  If he does intervene surgically will this take care of the problem permanently or will it likely continue to recur?

Summarized question: Does methicillin-resistant staphylococcus aureus stay in the skin?
