My relationship with my golf swing was going well until it wasn't. In early October I hyperextended my thumb on my glove hand during the transition. We had just played 18 holes and were playing a few extra holes before heading home when it happened during a routine driver swing. I kept my thumb immobilized for 6 weeks in total to give it a chance to heal. Four weeks after I initially hurt it, I found out that nothing serious had been injured. The worst of it was the tenosynovitis I had developed and the joint stiffness associated with the sprain. Good thing it was at the end of the season. It's taken nearly 6 months to completely resolve. I can finally grasp things like a peanut butter jar again.
As a self-proclaimed tinkerer, an injury like this at this stage in my life presented a unique challenge. I had to first rehabilitate my thumb and make it functional again so that I could return to work. Then I had to decide whether I was going to put my thumb back on my grip the way that I always had.
During this process, I had a lot of time to think about the how's and the why's. I couldn't remember a time experiencing any thumb pain post rounds or during shots. Obviously, the moment my ligament gave way and my muscle strained was the moment that told me I had exceeded my capacity. My parts failed.
Poor concepts often lead to poor performance. I had to examine my grip and everything else that influenced me to adopt that grip. It forced me to examine my fundamentals. Ultimately I had to figure out how to have a functional grip without putting significant pressure on my thumb. So over the past six months, I rebuilt my golf swing literally from the ground up.
