Erythema Multiforme Skin Disease Causes Red Skin Patches, Lesions, Blotches for Rash Treatment

Erythema multiforme is a skin disease that causes red skin patches, blotches or whatever you want to call them. The lesions are usually circular or round. And erythema multiforme can also affect your mucous membranes found in the lining of your mouth, digestive tract and vagina.

Erythema multiforme red skin blotches appear suddenly, typically causing multiple patches to break out on both arms and/or legs, then they spread inwardly. Although, this skin disease rash can turn up on your palms or soles as well.
