There is a lot of confusion out there about CTS and RSI. Only by rigorous testing can a doctor tell you the difference.
And whilst some supports which help both to a certain extent, supports will not cure CTS but might rest your hands for long enough to cure RSI.
A simple but not definitive way to tell if it is CTS is to gently rub the pads on the tips of your fingers against the edge of your teeth. If you can feel more through the little fingers than the other ones then it probably is CTS as the nerves caught in the tunnel from the fingers to the brain do not include the little finger. The definitive way is for your doctor to measure the current going through each finger.
