I have a rash on both arms and from my knees down. no where else. I have gone to a dermatologist and are now sending me to an allergist...This has been happening since Feb. 2nd. I needed a break and asked for predinizone which helped for two weeks and then it came back after I weened off of it...
I would recommend continuing with Prednisone or some other steroid on consulting your doctor. You can also take some anti-allergic like Cetirizine and see if it helps. Sometimes applying ice packs can also help in case of allergy. And I would also suggest a visit to an allergist to determine the causative agent for this allergy. Hope this answers your question, thank you.
