Sorry I couldn't get a better pic. But its like small bumps that feel like small pimples clustered in a small area of 2 patches. Its the size of about an inch and a half on my neck. They came out of no where and I've never had anything like this. I don't have much back acne, small pimples once in a while that come and go. Is it a rash or acne or some type of skin disorder?
