I have been struggling with this for several years with the throttle had going numb occasionally. After I had my CMC surgery for osteo arthritis in my right thumb the carpal tunnel became much worse. A year after the CMC my recovery was full with good mobility and strength, but the carpal was very aggravated. I had the fix surgery done on the 5th of Sept and I also got a trigger finger release done on the ring finger. I had the stitches removed this Monday and was able to use the hand some what during the recovery period. The best news is I finally got out on the GT today and rode for over an hour with absolutely no numbness. I am really glad I had this done as I could not ride for more than 10 miles without the right hand going numb.
