I had a bit of a pinched ulnar nerve a few years ago. Numbness, tingling and such where it creates the problem in the hand.
What's interesting is that before this I was taking a couple supplements and wearing a wrist brace for carpel tunnel while I waited (4 months out) for an appointment to get a "nerve test" - and by the end of that time I actually cancelled the appointment as my carpel tunnel was gone.
When I pinched the ulnar nerve I took the same stuff for about six months. For the most part it helped the pinched ulnar nerve. I've completely forgotten I've had any problems (if I think about it I can still feel a bit of numbness so it didn't completely solve the problem).
One supplement was called Bromelain if I remember. I will look to see if I have both still and pass along what the other one was.
