I have a pinched nerve in my neck & shoulder that causes me to lose feeling in my right hand. I wear splints at night so that I don't have to wear them during the day (they keep me from curling my hands up under me while I'm sleeping.)
Otherwise, ibuprofen (Advil) or naproxen sodium (Aleve) if you're able to take them, and ice, and don't over do it.
*edit: Oh, I forgot to add that I'm 'young'n', so I've got years and years of fun with pain ahead of me. :-\
