Im 12 and my fingers are bloody sore. ha ha get it. yeah,mine hurt as well. before i couldn't write with a pen at school. but i kept playing and playing and playing. and now they are strong as. i can poke a pin into my fingers and i wont feel a thing,it is so cool. so my advice, even if its painful keep playing and you will get there.
good luck dude. let me know how you go.
