A few years ago, I had acute pain in my right thumb. It was diagnosed as tendonitis, likely from overuse with my computer keyboard. I received a splint to help stabilize it and to avoid the pain from moving it. It was very difficult for me to work since it was my dominant hand. Around that time, Beverley offered a hand workshop which I signed up for. In addition to the workshop, I did some private hand sessions with her. I did the exercises faithfully for a few months. The pain went away without the need for cortisone shots or, even worse, surgery. I have not had pain since even though I continue to use that thumb on a regular basis when working. Occasionally, I start to feel a twinge of pain. When this happens, I start doing the exercises again and ward it off. This has made a huge difference in my life.
