You're not being a doorknob. D8 also fought MRSA for years, she would get cysts on her bottom and they think she carried it in her nose. Go to a specialist. I finally got my D8 into the practice's infectious disease specialist and he had it gone after one round of a new-to-us antibiotic. This was after 3+ years of off-and-on treatment with her regular doctor.
