I have non-stop itchy skin on my feet and hands, also some on my leg. It can leave rashes.What is it?

Doctors don't know exactly what it is.|||I have that itchy skin an my hands as well.......I take two benadryl caps every 6 hours it helps,a lot......also the down side.....will make you sleepy till you get use to taking this|||Maybe it's psoriasis. You should ask to see a dermatologist and get a proper diagnosis. Either way he/she would know best if it's a skin condition.|||use goldbond lotion|||It could be an allergic reaction to something in the air or something you use to wash clothes with.|||It could be an allergy to something, have you changed anything you wash clothing with? It could also be a food allergy, try to log what you eat and when things itch. Possibly the rashes are from scratching the itch? Some fabrics can be troublesome too, have you bought any new clothing? Sometimes the starch in the new clothing causes troubles. Have you had any tests for circulation problems? Illnesses like diabetes can make for itching too, I'd go back to the doctor for some tests, possibly allergy, definitely blood work to check diabetes, and then maybe go to a vascular doctor to rule out vein problems, they can make neuropathy, which can make things itch too.|||its probobly just a rash, or you might have ezemca (dunno how to spell)
