ok, this might be a bit of a weird question…
for the last couple of days my right thumb-joint has started hurting, like I sprained it. thing is, I can’t think of anything I did recently that might have brought it on. I have been upping my guitar practice of late, and have been practising different picking styles, but my thumb doesn’t actually hurt when I play…!?
I might lay off for a few days to see if it improves, but I was wondering if this is a likely source of the pain, to those who may have some expertise in this area, obviously.
