One afternoon red spots and hives showed up on my hands, both on the palm and back of hand. since then, they are speratic and come and go. tammy?

Contact allergy: What you described suggested allergy to some thing you came in contact with. Try to keep a note of the things that you may have touched prior to the rash to discern if there is a pattern or if you can identify a product that causes the symptoms. If you identify, then you may wish to challenge yourself and if the product causes rash you will need to avoid it.
