I had CTS surgery two summers ago - right hand first, and then left hand 6 weeks later. It was life-changing! When my hands weren't numb, they pained. I didn't have a good night's sleep in years - the pain and tingling would wake me up and then I'd have to get up and walk around with my hands hanging down until the tingling stopped. I didn't quilt for 8 years because of the numbness. I have not had a problem since the surgeries. I don't have much strength in my hands but at least they don't hurt anymore! :D
