question: Hi Doctor; I have a itching rash all over my body even on scalf I went to my M.D. and all she told me was I had come in contact with something that didn t agree with me. She gave me shot and pills called hydrOXYzine HCI 25mg that I took before I went to bed. The itching hasn t improved at all. I have been putting cortizone cream and that helps about 30 minutes then it starts all over. I am miserable and I don t have a clue as to why I have it. My friend said to take a baking soda bath. Can u help me with this itching problem that won t stop.
