Suggest Treatment For Rash In My Face

Hello, I was recently diagnosed with a staff infection, but my GP didnt know which one. The rash on my face has clard, but Im very worried that it has infected my bloodstream and my private parts are swollen, my neck is also swollen and the inside of my mouth is covered in the same soars that were on my face. My eyelids at the top and bottom are also filled with pus and are very soar.Also, when I hold my breath, I can actually feel the soars 'popping' inside my body. I know that these can be really dangerous, what should I do? Should I get an emergancy appointment with my GP, or will my immune system just fight it off, It has been going on for a while.
