Hi! My name is Tracy and I have been Diabetic for almost 10 years, however, I take medication by mouth which seems to really help control my blood sugar. My problem is I have a wound under both feet that are healing very slow. The one blister under my left foot has been there over a year; the other blister does show signs getting better, but it has been there almost a year. I am very careful to make sure no infection sets in on either foot. Does anyone else have a problem with wounds healing very slowly and, if so, how do you treat it?
