[quote name='allighatt0r' post='502127' date='May 31 2009, 10:13 AM']About a year ago, i switched from being a pick player to a fingerstyle player, mainly because the joint of my thumb nearest the fingernail is doublejointed, and bends too far backwards, so i can't hold picks properly. Also for tone reasons.
Anyway, at my gig last night, about halfway through the second set i started getting pain in the knuckle of my forefinger while i was playing... I don't think there is anything wrong with my fingerstyle technique, i keep my fingers perpendicular and my wrist straight, but i was wondering if anyone else gets this, and if there is maybe a detailed "how to play fingerstyle like a pro" article about so i can look at learning from the ground up?[/quote]
It may be that you play too agresisively straight off and need to warm up your joints first? I always think its best to move all of your finger joints a little to play a note than to over-extend one joint to do the whole thing. Equally I'm not sure that perpendicular sounds ideal anyway.
I would recommend alternate heat and cold on your joints to calm them down (hot water bottle or wheatbag, then bag of icecubes, alternating). You may also want to try ibuprofen as this has an anti-inflammatory effect.
