i'm 16, and i should have taken a day's rest from piano about 6 months ago when my index finger in my right hand started hurting a little bit, and because i didn't, its spiralled out of control to the point where i cant tie my shoelaces, can't write with a normal pen (my doctor made me one that i can use) etc due to pain, and extensive medical advice has told me that this kind of thing cannot ever be recovered from.
clearly i'm not invincible, and neither are you. i dont want to let this happen to somebody else.
stop playing.
