Hi, I have a history of diabetes in my family on both sides, so that's why I have been particularly disturbed about a sore on the side of my foot that just won't go away. I noticed it about a month and a half ago. For a couple of weeks I put it off as a corn, but it has started to sting a little when I touch it. It is dark around the outer portion of it and in the middle it sort of dimples. Could this be the beginning of a boil in your opinion? Or maybe as simple as a cut I failed to notice.

Sincerely ,
