I Have Lupus, Thalassemia, And Weber Christian Disease. I Waz

I have lupus, thalassemia, and weber Christian disease. I waz diagnosed with mrsa on my scalp in December, with excess iron. Today I noticed a sore with a black ring around it in my hystorectomy scar. I had surgery in 2009. Anyway it is hard to the touch with white puss like a pimple, but flat to my skin. Does this mean the mrsa isn't gone?
