Sir/ma'am I have a wound on my middle finger of left hand present since past 3-4 months. It's not healing and my hba1c is normal i.e. I am not diabetic or pre diabetic. I got this wound doing some wooden work, and had a very very small wooden particle getting stuck in it. I tried to removed it but it didn't got removed, and I don't know whether it is still present or not. I am attaching the photograph, kindly guide for the required action.
