My left wrist hurts. Really badly. Doctor's orders: voltarane gel (anti septic, muscle relief and good for burns/stings/skin fungi/etc.), and bandage the arm so that I won't play move my wrist much.
My wrist has been hurting on and off ever since, but never in such a scale that it completely disables my hand. It hurts even just typing.
That which is neglected tends to grow. That saying was written in graffiti on some wall in Tel-Aviv. Apparently, there is much truth in it.
I feared that it was caused from my 7-string. I don't have large hands, and I tend to play my guitar very low. Also, it started a bit after I got my 7.
I went to see the doctor about it, and I told her about my playing, and when I told her where I work at (dairy farm), she said that it is much more likely that I got it from there (I also started working there around the time of the initial happening). This makes me feel much better, since I'd rather develope a vicodin habit than give up my extra string.
The worst part? I'm working on a new track of mine, which I really like and am very proud of, and the muse for it has been slagging me with a baseball bat lately, and now it all grinds to a halt.
The even worse part? The dude who writes bass for me, who already has arthritis for a very long time (he can still play, but not for a very long time, and he has a bandage on his hand during the day) just got another infection in his other hand, so he's disabled aswell.
The worse worse part? I didn't get any good painkillers...
I've heard a lot about stuff like that. I went to a doctor a year ago or so, because I was getting extreme pain in my wrists when I played. He told me that it was probably my playing style, and I was running the risk of Carpel Tunnel. He told me to talk to a guitar teacher about my technique, and sure enough, I was playing the guitar wrong, which was damaging my veins in my left wrist.
Maybe you could talk to a guitar tech, and show him your technique to see what he says. Does it hurt as much when you play a six string?
