Thanks for all the comments.
I say that people with diabetes who have black scar color?
1. Because my mather has diabetes.
2. I noticed that my mother's. The wound healed and became black.
And I say that but I understand that. People with diabetes if has the wound. Wounds are very difficult to heal.
1. My mother has undergone surgery. After the diabetes. The treatment of wounds on the right hand takes a long time.
2. After the wound healed. The skin wound area becomes black.
Symptoms of diabetes vary. I understand.
I noticed from my mother.
It is a fact.
Thank you.
