This rash started 2 days ago on my arms, it has since spread to cover my arms, chest, stomach, back and neck. At first benadryl was working but now it is not getting better. It is slightly red and blanches when pressed. I tried using hydrocortisone cream but it stung so I washed it off. It's painful and itchy. I am hoping to wait until the morning for urgent care, instead of going to an emergency room now, as I am uninsured. I do not feel dizzy or lightheaded, and I don't feel any shortness of breath at the moment. My mouth/throat is not swelling.
