I did something to my index finger on my plucking hand when tying shoelaces abou a week ago that made the nerve really sensitive. While I was pulling the lace it was against the middle knuckle in that finger and felt similar to the sensation you get when you hit your funny bone. Now it’s spread down to the finger tip so that it’s tingly even when I’m tapping a phone screen. In fact just walking around it tingles and feels sensitive. The reason I fear CTS is because my wrist also feels kind of tight. I keep getting the urge to spread my fingers out as if that will make it feel better (but it makes no difference). I play finger style but thinking maybe I should use a pick until this improves. Any ideas?
