Phil Gaynor The first thing I would do is what Tainojim suggests then I would find a Drum teacher and see if your holding the sticks wrong somehow, if that don't work you may have Carpal tunnel in your hand, that's not a big deal I had that 2 years ago and now they do surgery with a scope it's called Arthroscopic, healing time is very fast my wife had both hands done 1 week apart, you can see the procedure on youtube.com that's if it is Carpal Tunnel, in the mean time you can get gloves that are made for people that have problems with their hands type in
Triplet Drum Glove their worth the money I bougt a pair when I feel like not using my hands very much as crazy as that sounds.Send me an e-mail and let me know what you think PS THERE'S A VIDEO YOU CAN WATCH BEFORE BUYING ANYTHING.
OH AND BY THE WAY MY WIFE IS IRISH GOOD LUCK SLINGERLAND
