I have had a horrible rash since before Christmas, arms, chest and shoulders. Feels like someone has thrown acid on me - blisters keep popping up randomly or in pairs and then they go lumpy and the itch is unbelievable. 5 days of steroids in Feb helped but it didn't clear. Still using E45 and Aveena - soothing for a few minutes. I have an appointment with a dermatologist but not for 2 weeks. I do have another 5 day supply of steroids but don't know whether to take them before the consult or just try and manage the discomfort with massive doses of antihistamine. Any advice would be so welcome- Dr. AGoogle has given me lots of things to choose from diagnostically !!
