I have been getting hives almost daily on my hands and forearms (most of the time they do not itch). nothing helps. what could it be?

Hives: Hives or urticaria, can arise from multiple conditions or triggers. Things like pollen, dust & dander are the usual suspects, but they can also arise with cold air, stress and anxiety. Depending on how long you have had them & keeping track of possible things you are exposed to cause them, you should see your doc for a in depth history & physical exam & likely referral to at least an Allergist.
