About 2 months ago I was had a staph infection in my hand. I had to be hospitalized because it was a really bad infection, in the meantime, while in the hospital I got Mrcr infection. I was treated with anitbiotics and released. Now a month later, I had patchy scabs inside my ear, which I also had while in the hospital and then behind my ear I noticed a lump. It got bigger and redder. I went to the doctor to find out it was Mrcr again. Is it possible that the first infection I had never left my body. causing me to get the same infection again?
