I have a chronic breakout on my face, arms and hands. My face breaks out, and the areas break open with a dark brown, very hard circular discharge. They force themselves out, leaving a hole in my skin. Then they reoccurring. Could this be calcium? I have MRSA that affects only me. It is not contagious. I have a severe case of cellulitis on my abdomen , but the wounds on my abdomen are much larger and have a pasta like or white discharge. My face has wounds that forced themselves out end the wounds are always discharging round very dark brown circular objects that are very hard.
