I'm currently dealing with tingling types of sensations in my left hand pinky after playing my English.
Note I rest the left hand side of the concertina on my leg. Usually it is not a problem while playing, the
sensation comes after I stop or the next day. I've also had it crop up from playing guitar as well.
I spent quite a while, just playing individual notes slowly, really concentrating, and monitoring my hands for any tension or extraneous finger movement.
Though a useful exercise in it's own right, it didn't really help with the tingling sensation.
I now think the problem has something to do with Ulnar nerve entrapment, and
so the issue could be further up my arm(s) rather than in my fingers/hand where I feel the problem.
So far, I haven't gone to see a doctor, I haven't been playing much lately to try and recuperate, and when
I get back into it, I plan on just spending a bit of time making sure that I'm not tensing up anywhere (right now I think
the problem is that I'm tensing my upper arms against my torso).
Anybody else dealt with this problem in their pinkies?
