Urticaria, also commonly called hives may be related to allergy, stress (emotional/physical), heat, cold or exercise. You should try moisturizing lotions and some
over-the-
counter antihistaminics like cetirizine or loratidine. Anti-itch creams such as diphenhydramine (benadryl) may provide relief.
Another condition can be eczema. It includes a variety of persistent skin conditions which cause dryness, redness, skin swelling, itching or bleeding.
