Did you know that when you pinch your index finger and your thumb together that 14 times that amount of pressure is placed onto the base of your thumb? That means that simple tasks like opening a milk jug can place 140 lbs. of pressure on the base of your thumb. If you have thumb arthritis, that can really hurt. BoulderCentre for Orthopedics & Spine has solutions for you.
