What do you recommend for a severe case of poison ivy on my face, hands, arms, neck, chest, buttocks, groin area? I went to a local old doctor, he gave me a shot of prednisone, and a packet of prednisone take 6 pills then 5 pills 4 pills etc until gone.....it is not helping, I have dealt with this for a week now, and can hardly take any more, I have a hair brush using it to scratch in between my fingers right now. It s driving me to the point of no return. ....
