Re: How far
I ask myself the same questions. Since I don't have a confirmed diagnosis, I can't look up a specific disease to get any ideas.
I am in the same boat, watching my capabilities slowly deterioriate.
My newest challenge is parting my hair every morning. My arm is too weak to do it like I was doing even a week ago. It's taking all my skill and acrobatic twisting to get it done.
I feel for you. I really do.
