@brendaharris Mupirocin is often prescribed for suspected staph infections - I had a leg wound that responded nicely to it. My husband had a diagnosed staph infection on his back that had not responded to anything for years - 2 courses (about a month) cleared it.
It is also prescribed sometimes for nose sores that refuse to heal with more conservative treatment. It is known as an "off-label" use but it worked for me when a lingering lung infection knocked down my immune system.

Is the sore on your toe an ongoing issue?
