Pressure sore problems

I went to the doctor abou. T my pr essure sore I have to stay in bed most of the time now. It is a fungus and the spores spread under my skin. My wife showed me a pic. The medicine she rubbed on it makes the spores show up as red. A picture totally freaked me out. I won't be able to post much because my bedroom PC has lost the use of the microphone so I cannot dictate or control the PC by voice.
