One day I was playing some hard driving jazz and i got pain in my right wrist that hurt so bad I had to stop then and there. I bought this brace on a friends reccomendation as a stop gap measure until I could get to the doc. Once wearing the brace no more pain and never did go to the doc. I wore it for about 3 months and now play with it. Once in a while I get a twinge and know is it time to shut down for the day/night. It is then ok the next time.
