hi, wasn't sure where to post this. in the last week i have started experiencing pain in my left wrist along the pinky-finger side. it's a dull sort of throbbing pain and i am certain it is from playing/practicing double bass. clearly it must be a technique issue, though i can't figure out exactly what i am doing wrong. my teacher has noted that i tend to grip the bass too tightly and tells me to relax my left hand, though if i exert less pressure i am unable to get a decent sound. i use medium-gauge spirocores and the action is not too high. would switching to a lighter gauge maybe help? what else can i do to avoid making this problem any worse? thanks in advance..
