As a teen i started getting skin patches on my neck and chest. Dry not itchy or anything. Just wondering what it could be. I’m now 27 years old. So its been happening for some time now. I was once told by a Dr not being checked just her opinion that it could be because my body produces to much insulin. I’m no Dr but i just think that’s not what it could be. Id just like answers and to see what i could possibly do about it.
