I am really worried about my boyfriend.....About a 6 months ago, he had what was diagnosed as a staff infection on his face. Then Two others appeared in the next months..which was only to then be diagnosed as a bacterial infection that nothing has cured. A few months passed and then he started getting the same thing on and around the knee. They only appear one at time and look identical to a pimple with a lot of redness surrounding it, and then grow in size to about golf ball size, making him very ill. Each one will last about a week and then another will appear near the same region. This is a very big problem and he is in a lot of pain, and unable to function when they appear. PLEASE HELP
Optional Information:
Male , Age: 27
Already Tried:
antibiotics, that have either not been strong enough or broke him out in a rash.
