I developed nerve pain in my wrist and thumb joint -- probably due to playing too many games on my iphone. The pain became bad enough to send me to the drugstore for a wrist brace. I started taking my b12 and 100mg b-complex. Within a couple of days, the throbbing pain had eased considerably. By the end of the week, I was actually taking the brace off for part of the day.
