Hi I am a (47 year old male) heroin addict and have used for approx 20+ years. I have poor veins and mostly inject in my legs. I developed several small abscesses. All seem to be healing except for 2. One is a small oozing sore that has not healed in approx 2 months. I am in overall good health.

I was admitted to a hospital and was given IV vancomicin for 4 days then discharged. I was told that my general health is fine, no high bp, no diabetes, no septicemia, no endocarditis, good circulation, no blood clots. I was diagnosed with MRSA. Since my discharge, I have developed another abcess; it is approx 2"x3" and the skin is separating from the edges and the center skin is now BLACK! I was given bactrim when I was discharged. I'm scared.
