I was prescribed rifampin to treat a staph infection on my left breast. I had open heart surgery 10 months ago, and believe I picked up this infection in the hospital ( was there for a month, due to blood clots following surgery). Could this have been in my body for 10 months, and will I be free of it after this treatment? It has been so painful that I thought something had gone wrong with the heart surgery since it concerned my left breast, in the area of the incision. Please ease my mind by giving me some helpful insight. Thank you.
