Hi, I am 33 years old male, met with a road accident recearly. I got scrapes on both my palms, right knee & ankle. (Attached the photograph of right palm & ankle wound). My concern is that though it has been 3 weeks since the injury, my wounds are not healing fast. I am not diabetic which I got tested just 1 week before the accident. I have been diating since two months before the accident. I am worried very much what is causing my wounds to heal slowly. Kindly suggest what may be the problem & how this problem can be treated.
