Lately I have been having discomfort in my left hand/wrist. I have tried playing at many different heights but I can't seem to get my wrist to not bend so much. could I just be stressed out from school and work? and in turn just not be relaxed enough when playing even though I think I am? This never used to happen but all of a sudden I can't even do basic chromatic scales using one finger per fret style fretting without having left wrist pain and just making me frustrated.
