I have been itching like crazy to the point where I am scratching myself till I bleed for the past week. They have given me hydroxizine and prednizone to try and help with the itching but it will not stop, it just continues to burn, I can t sleep, I feel like I am dizzy and going to throw up. I have tried every OTC lotion, benadryl, zyrtec. Nothing seems to be helping me and I cannot sleep it is keeping me awake. What can I do?
