I woke up to itching palms, as the day went on the backs of hands also were itching. There was no rash. By evening I had very bad heartburn, which is not something I normally get. By the next morning the itching was moving to different area s. In the groin area under the armpits, back of the neck. The heartburn so bad it hurt to swallow my own spit. Then I started getting raised bumps, kind of blister looking in itchy area s. This is going on day 5 of this. What is wrong with me? I can t sleep I am so uncomfortable!
