Basically, about a month ago, I started noticing
weakness in my left
thumb. It was slight, but distinctly there. Over the course of the weeks since, that weakness has spread to my left pinky, left forefinger, right thumb, right ring finger, and right pinky. The rate of progression has increased recently and today, I had trouble squeezing a mustard bottle with my right hand (my right pinky would essentially collapse flat at the 2nd hinge from lack of strength).
