I am not sure what has happened. The fingers of my left hand, especially the baby finger have grown stiff. I learned to touch type when I was 13. Can’t do it any more. my left fingers won’t bend and flex to work the home keys properly. Had a talk with my family physician about it this week. We have other fish to fry first. A steroid shot to the finger might be in order, Typed this touch style with right hand and one finger using left hand. Strange.
