11 years ago, my left index finger was caught in a table saw. After some miraculously good surgery, the fingertip recovered its shape, with barely any scarring. Within six months, I was playing normally, and continued to do so for frequently (several times/week) for the next six years.
After a five-year hiatus (during which I would play briefly every couple of weeks), I am back to practicing daily, but this "sawed" fingertip (and only that one) is now experiencing sharp pain after as little as 15 minutes. I am playing .12 to .53 acoustic strings.
Do I just need to give it time for callouses to rebuild?
