Suggest Remedy For Scabs

mark on my shin that looked like a bug bite and then turned into a scab. There was one "bug bite" then another one. I was in the hospital for 2 days. A culture was taken- negative. Now-2 biopsies first no result --awaiting 2nd result. They have scabbed over, but do not heal.

By the way, had a pedicure before the trip to California. It's since March
