What it takes: Hand, wrist and finger tendon strain
Pressing strings with a bent wrist and gripping the neck tightly loads the finger and thumb tendons. Sudden increases in practice time are a common trigger for pain.
Hours of fretting, strumming and holding an awkward posture.
Playing an instrument is good for your brain and your mood. The body cost comes from repetition and posture. Fingers press hard on strings for hours, the fretting wrist bends sharply, and the neck and shoulders hold one position. Loud amps add a risk to your hearing.
Pressing strings with a bent wrist and gripping the neck tightly loads the finger and thumb tendons. Sudden increases in practice time are a common trigger for pain.
Looking down at the fretboard and hunching over the body of the guitar pulls the head forward and lifts the strumming shoulder. A strap set too low adds strain.
Amplified rehearsals and gigs often go well above 85 decibels, the level where long exposure can damage hearing. Ringing in your ears after playing is a warning sign.
Keeping the fretting wrist sharply bent for long periods can press on the median nerve. Numbness or tingling in the thumb and first fingers is the usual sign.
See a doctor or hand therapist for numbness or tingling in your fingers, pain that lasts after you stop playing. See an audiologist for ringing in your ears or muffled hearing that lasts. Fingers that curl or won't respond normally only when you play can be musician's focal dystonia, a nerve problem. No exercise is known to prevent it. If it starts, see a neurologist rather than practicing harder.
