So, the doctors just said too bad? We can get skin infections, things like cellulitis in that area. If a small amount of staph gets into, for example, a tiny break in the skin there, it can cause the layer of skin to become infected. Not saying that is what it is but it definitely could be considering it wasn't from friction or anything like that. I would go back to the doctor and not leave until they have a plan. You may need antibiotics if is indeed a skin layer infection. good luck
