I notice it is much worse if I sweat or if I wear lotions that cause my upper arms
to sweat. Unfortunately, like every one else explained, scratching the skin
only worsens the itching, and then the topicals we use don't work. There is no rash, and I also think that is what contributes to doctors thinking it is psychological. I have been using Gold Bond Lotion for itching, with menthol in it. Unfortunately it is a lotion, which sometimes creates more sweat.
