I am unsure if I have carpel tunnel, can t say that any symptoms wake me up. But over the last few months I have noticed that my index finger on my right hand (mouse hand) is always swollen and it is difficult for me to bend it. I can no longer use it even open things like a bottle of pop or water. My thumb on my right hand also seems to be affected. Any ideas on what could cause this? As an additional FYI - the finger is always swollen, huge difference between the right and left hand.
