Don't freak out! You are perfectly fine, I had the exact same thing about a year ago. Its called Psoriasis Rosacea, if I remember correctly. The pictures online are awful and misleading, so my advice is don't look at those.
If this is the same thing I had, it starts as one big spot that gets red and dry. Then soon turns into a bunch of little spots, sometimes itchy, sometimes not. What my doctor told me is to take antibiotics, and use eczema lotion or cream. Along with oatmeal soaps, scrubs, and/or bubble baths.
I still recommended you go to the doctors incase it is something else. Or if not, to get the antibiotics.
best of luck! (:
