What causes rid of a staph infection when med's don't work?

Staph infection: If the infected area is localized, applying warm packs may allow the infection to come to a 'head'. At that time your doctor may excise the infected tissue.

Depends on the Med: I would ensure the right medications were used. If you have an abscess, it needs to be drained. Many staph are resistant to antibiotics, but there hasn't been a case of staph with proven resistance to everything. If you mean you keep getting recurrent staph infections, there are certain ways to attempt decolonization of your body of staph. Talk to your doc.
