Work on it: PR self heals over several months. Scabies rash and itching is due to a reaction to the poo left in tunnels in the skin by the scabies mite. It gradually improves after all the mites are dead and quit making poo. Regular OTC steroid cream can help the scabies rash and an occasional soak in cool water with oatmeal powder can aid the itching.It takes weeks for the itching of scabies to fade.

May be neither: The two aren't really ringers for each other. The first concern with an itchy rash is that you're taking some kind of medication (including some "natural holistic remedy" that may not be what it's labelled). It's not erythema multiforme, is it? Another common very-itchy rash with the symmetry of pityriasis rosea is dermatitis herpetiformis. Maybe you need a "derm" consult. Best wishes.
