I have what appears to be a ganglion cyst on my left wrist. It has been there for a few months and they usually go away by themselves ... except mine appears to be putting pressure on a nerve as for the last couple of days I have had a "pins and needles" type feeling in my left ring and pinky fingers. I saw the doctor today and she has referred me to a specialist who I am seeing tomorrow afternoon for assessment. I am not sure whether he will aspirate the cyst or suggest surgical removal. In either case, I probably will not be able to use my left hand for a few days. No typing or stitching - thankfully I can still play The Sims 2 as that only requires the use of the mouse and my right hand - lol!
I will update you when I can :)
