Burning skin... (I've had itchy burning hands and soles of my feet)
First, I'd spend the money on CeraVe' Soap, it's at the drug store, for your hands and the shower...
Also, a 24 hour antihistamine, Allegra is the best then Zyrtec then Clariton, take any of the 3 that you can tolerate.
Also, stay out of the heat, bright light bulbs, cover your self with a light shirt and pants.... a hat but you do not need to get heated like sweating....
