I have intracable itch of idiopathic orgin, persisting for 2-1/2 years. I have yet another appt. with perhaps the ninth doc coming up. Have been treated with many different ointments, systemics, light treatments. It occasionally was alleviated, but never went away. I an tired of being itchy every day of my life. Skin looks like severe sunburn, very dry in spite of heavy use of Cerave, lubriderm, etc. Arms and legs also swollen.
