Red spots all over my body mainly on the inside of my arms, shoulders, chest, and back. Patches that are red some raised and darken ovr time, itch ocas?!

Rash?? Please go see a dermatologist -- rash is hard to describe but it must be observed and sometimes biopsy is taken.
Red spots on skin. If lesions are bright red, small (1 to 3mm) with no symptoms they are most likely cherry angiomas. If pink , scaly or itchy, it may be a rash and you should see a doctors if the lesions persist.
