Hi, my neck in the back has been black and itchy since i was like in high school, i have always been an over weight person. recently i started noticing more red around my neck and its itchy. what can i do?

Loose wt would be the best thing to do initially. Then try applying Vit E to the affected area. Good Luck

Hello, that is called acanthosis nigricans and it is due to obesity and insulin resistance. It is a good sign that if you're not diabetic you may be soon. Weight loss is the treatment and can reverse the skin effects that come from high levels of insulin in your blood.
