Dealing with Burning Sensation in My Hands

what is the best way to deal with the on off burning sensation I'm feeling in my hands? it's only in my hands, and it started when something cold would touch them, like cold water or air, which it still does, but now if I get anxious or stressed they feel on fire. I don't know what to do. I'm in a family emergency situation so I can't just get away from the stressor.
