Excellent news about Kevins NCV. You can’t ask for better than that. As far as his ankles, I have the same problems. In my case, I think its the achilles.
when I overdo it they hurt. its seems to be sloooowly diminishing.
His hurt when he is sick though so I don’t know for sure about that but it is
probably where his body hurts when he isn’t well.
Just wanted to pass on that I am happy for him and your family on this
