So..I have a "Jersey Finger". Which has nothing to do with The Sopranos. Hyper extended the finger opening up a car door and I did not go to the doctor as soon as I should have. So given time or surgery playing certain chords is difficult and some barre chords and open tuning stuff hurts! Anybody out there ever go through this? Any other hand problems and how do you cope with it?
