Stop squeezing the stress ball!
STOP SQUEEZING THAT STRESS BALL!
Some people have a stress ball or tennis ball that they squeeze to relieve them of some aggravation. That’s fine.
But when someone has an elbow/wrist tendinitis, squeezing a stress ball hurts but may also be contributing to the injury!
The forearm has muscles that flex and extend the elbow, wrist and fingers. There has to be adequate muscle balance between these muscle groups much like having a proper balance between pushing and pulling muscle of the shoulders, chest and back.
By continuously squeezing a stress ball, you are re-enforcing the finger, wrist and forearm flexors making them stronger but ignoring the ones that extend the fingers, wrist and elbow!
QUICK FIX:
Grab a thick elastic band (the ones you find around stalks of broccoli), place it around your fingers and open and close your fingers. Simple. Do this until there is a slight fatigue in your forearm every day and you create better symmetry in your arm!
