I had CTS surgery 5 years ago not long after I broke my wrist. the braces never really worked for me since I was doing repetitive work 8-10 hours a day.That was the only thing that fixed it for me. I use a computer mouse and keyboard all day and by the time I got home cold not even think of quilting I was in so much pain. Had to have the surgery due to the CTS making my work too too painful. best thing I have ever done was the surgery.
I tried paraffin soaks and lots off different pain meds and anti-inflammatory meds.
But nothing except the surgery worked. Sorry I am not much help.
