I have spots on my back and head what could it be the spots on my head give me a headake?

I doubt the spots r: cause of your headache, but I would see dermatologist for diagnosis and possible treatment options:)

VisualDX : Hi, it’s hard to say without a picture but there is a great app that may be able to help you get a diagnosis without being seen in person by a dermatologist. The app is called VisualDX and is one of the best, if not the best out there. Many clinicians, including myself, use it. Just snap a photo and it gives you a list of possible diagnoses. Good luck!
