Hi Doctor Rynne, I Woke Up Four Days Ago With

Hi Doctor Rynne, I woke up four days ago with what looked like hives on my right arm .I went to local medic and got treatment . Doesn't seem to be working though. Today,two day after taking the treatment, I got same rash and itching all over my left arm and the rash is also warm on touch.My right arm is still in same condition and itching badly as well. I can't think being in contact with anything unusual. Glad to hear what you think.
