I suffered from ulnar tunnel in both hands for quite a while. Happened to be during a time when I did not have insurance. After reading a bit got some wrist braces that held my wrists straight and would wear them at night while I slept. That relieved it a lot, I suppose keeping the wrists straight at night allowed some down time for healing. It took a few months but I noticed that the problem went away finally. Keeping the braces tight also felt better on my wrists as well.
Try it it is worth a shot. I picked up the braces from a place that sold motocross equipment. These are what I used and they are specific to a side.
