I've been playing bass consistently since January and haven't had any injuries until now. I've had an intense pain in the first joint of my left hand pinky for the last 3 weeks. The finger hurts the worst when I play the D and G strings usually when I play the thicker strings it doesn't bother me. Most days if I play through the pain for ten minutes or so it goes away, but then the next time I go to play it's back again. I got a Fender Precision bass off of ebay and it has earnie ball hybrid slinky strings on it. There is no pain when I I'm not playing the bass I can bend it and put pressure on it with no problems. If I take my other hand and place the pinky on a string with it and then let go there's no pain even though my pinky is holding down the note with it's own strength. It just doesn't make sense. I've been trying to stretch it, but nothing seems to help. I would think it might just need to get stronger, but if that case how come it's never bothered me before. It feels normal to the touch and it looks normal, so I can't figure out what the problem is. The only changes that I can think of since this pain started is that I have a new bass (I used to play a Stagg BC300) I have different strings (I used to use GHS strings) and that it's usually cold in my house now that the weather has changed and therefore my fingers are usually cold even after playing for a few hours. Could any of these things cause my problem. If anyone has experienced something like this and can help me I'd really appreciate it. Thanks.
