recently my finger tips are being torn to shreds like i can see 3 or 4 layers torn open. i got a new guitar and got erner ball super slinkies .09s when before i always used yamaha .1s could that be the problem. Or since i am still new (2 1/2 months playing) could this be what should happen? But my fingers did stop hurting earlier at about a month into it and now its starting up again with the new strings. Or could it be since i got my wisdom teeth taken out and i now have an excuse to sit there and due nothing so im playing like 8-12 hours a day?
