I've started noticing pain in the first two fingers of my left hand (fretting hand - I'm a right-hander). Doesn't seem to be getting in the way of my playing much at the moment, but there are the odd times when I have trouble making the chord right first time because of stiffness. I'm 55. Does this sound like the moment I've been dreading, when arthritis or some other kind of joint pain kicks in, meaning I can't play as I once did? Anyone else experience something similar? Is there anything I can do to alleviate this?
