3 days ago I just started becoming very itchy all over. One day I broke out in a random rash on one arm and my whole hand, that went away fast. The itching still continues every where...my scalp, face, legs, stomach every where. I went to urgent care she put me on methylprednisone which hasn't helped and then told me to see an allergist. Im not about needles and wanting to see an allergist. I was fine and then woke up like this one day. the rash hasn't come back but now its like a tingly itch. Any ideas on what this could be plz help!!
