Hey guys recently I've been getting shooting pains in my picking hand thumb and after a practice session or gig it and aches all week and occasionally locks up until I have to click it back. It's got to the point i find it difficult holding a pen to write with. I might have to stop playing I'v started using my fingers more to compensate out of avoiding the pain but a past injury means I can't feel the end of one of my fingers so I can't really rely on that either. Just incase this is a common problem has anyone had this experience before? I've had problems with my wrists but that seems to have gone away and it feels similar to when I torn a ligament in my finger but Im pretty sure its not that because its not permanently bent down.
