She has a rash that has went from head to toe and a medrol (methylprednisolone) pack hasn't helped. stress makes it worse nothing else or time of day. not in private area.

Rash: If the rash is extremely itchy it sounds like a stress related pomphoylyx dermatitis. It may also a medication you are allergic to. If Medrol (methylprednisolone) did not help try drinking Tonic water. It has quinine which is a component of a drug called Plaquinol which helps with autoimmune rashes. You should be worked up by a dermatologist. Good Luck
