have a rash that comes and goes and is very very agitating.  sometimes i can feel it coming on and then a streak appears.   it occurs some during the day but usually intensifies at night time.   saw a local physician who prescribed predisone.    That may have helped a little bit but as soon as the predisone was gone the rash was back in full force
Hi.recurrent rash on and off can be acute urticaria. First rule out any allergens. Then use an antihistamine twice daily and add prednisolone if not cured. Go for thyroid test if still persists
