Sounds like psoriasis to me. GO TO THE DOCTOR! A year? Good grief.Here is a website with photos and information about psoriasis:

www.medicinenet.com/ringworm_pictures_slideshow/article.htmGO TO THE DOCTOR. If I hadn't mentioned that already. Take care of yourself, hon. Also, if it's ringworm it's highly contagious!! Take care of other people, too!Hmm..okay I did not see where you said your doctor said it was dry skin. In that case...go to a DIFFERENT doctor. Good luck!
