Several months back, I started to have pain at the base of my right thumb when I texted or typed on my smartphone.
I had tenderness along the joint line where my thumb meets my wrist. The problem continued to get worse…if I typed or texted on my phone for more the a few minutes, my thumb and joint would burn. I had just started using a tablet computer for my documentation, so was using my thumbs a lot more than I was used to type and text.
What was going on?

The researchers have not come to a final conclusion, as studies are ongoing, but smartphone thumb could contribute to premature osteoarthritis in the carpometacarpal joint of the thumb.
