Problem: Since about the middle of this summer, I've been experiening the oddest of sensations. When I play long gigs, or multiple gigs in a weekend, I can almost count on my index finger (or as I like to call, my Yankin' Finger) to be in pain by the end of the gig. The closest thing I think I can come to likening it to is either a bad cramp or a sprain. I've yet to see a Doctor, which will probably happen soon, but I was curious if anyone here has ever had an issue like this. I've taken into consideration a few things such as my technique (which my teacher and I both have examined and found nothing wrong with) and just plain overexertion. The only thing that I can think of is when it first happened, I was doing my pre-gig stretches and I fear I might have stretched wrong. I've been steadily gigging for about 4 or 5 years now and I've never had to deal with anything like this before. If anyone here has had an issue like this and what you may have done to correct the problem, the information would be greatly appreciated.
