Not sure exactly what I did, but I had a gradual onset of pain and swelling in my left middle finger starting Thursday night. Of course, I have a gig tonight. I can't come anywhere close to making a fist, and I don't know how effective I'll be at playing. I told the band that I need to keep things on the more simple side tonight. I'm wondering if adrenaline from being on stage will help out. Also wondering if I'd be better up loading up on painkillers or having enough booze to numb the pain without making me sloppy. I realize that neither of those solutions are ideal.
