Also, run a search on carpal tunnel, pay attention to where the relevant nerves are and don't put as much pressure on them when you ride. It may take time to change your habitual hand positions. ALSO, get some gloves with padding on the palms. I use technical work gloves made for guys who run piledrivers and other vibrating machinery,("Youngstown" brand,) they're just as expensive as cycling gloves, look exactly like mountain gloves and work very well. I hope this helps you.
