Acupuncture. I had a similar issue with my pinkie and ring finger on my right hand started going numb at work. I had an ergonomics specialist from my company give me a whole new setup, but the only thing that actually helped was getting acupuncture/massage 1-2 times a week for a couple weeks straight. One interesting thing I found out was that while I was having numbness in my hand, the nerve that was causing it was in my shoulder/upper back.
