Hi guys, I had to stop halfway through a gig last week and the band had to carry on without me... While I was playing, my index finger (on my fretting hand) curled up and I had to use my right hand to uncurl it. It became unusable as each time I needed my index finger (which was every other note!) it did the same. My ring and middle finger then started to do the same and I was just down to playing a one note bass line with my thumb. This is a real concern. Is this just cramp? Or is it a tendon thing? I tried to 'shake it out' but it wouldnt go and the hand became almost unusable for another couple of hours. This happened once before a couple of years ago. I do warm up before each gig. I *think* its because we play a couple of songs in F, which is a big stretch for me on the bass. Maybe if we play them in A or E that will help. I just wandered if any of you guys have experienced this or have any solutions? Ive heard buying a short scale bass might help. Many thanks in advance.
