I play primarily electric bass but have just started playing the upright for a corperate band. I have been pulling it out for one or two songs per night but Friday night I did my first dinner set where I played upright for the whole set and noticed afterwards that my left hand index fingertip was numb from the knuckle to the tip. We also had a gig sat and sun night that included dinner sets but I used my middle and ring finger more (with no numbness at all) but now it has beenalmost a full week and it isstill a little numb but not as bad as it was originally. I've read about carpul tunnel but I thought that effects the whole finger as well as the middle finger. Any ideas?
