I have had no changes in my medications for 3 years. I take webutrin, Prozac, prevastin, estrodal, and a water pill HCTZ-25/37 All of a sudden, I have intense itching all over. It goes from one spot to the next. It is like bugs under my skin. I scratch until I make bruises or scratch the skin off in streaks. I have tried over the counter creams, did not change soaps or detergents, I am miserable. I have red splotches all over my neck arms , legs, stomach, back on on my shoulders. What can I do
