I related so very much to this post.
I have never been one who possesses a large module of coordination. In school...lol, I purposely chose sports that required very little of it. I did Power Lifting, Field Hockey, and Volleyball; sports that I could fall all over the place, and still look like the rest of the players...lol, or Lifting, where I didn't have to do much more that certain standing positions in a coordinated manner. I have pains everywhere from the MS, and from RA which has caused powerful crepitence in the fingers, wrists and entire spine. I say nothing of the pain most of the time, so folks who know me are aware that if I get too quiet...lol, then something is going on.
I have the standard gait walk too...but I like to endear it with the term "The Ozzy Shuffle"...lol, because it seems to knock it down a notch or two on the scale of all things awful to to deal with. My Grandfather dies of Alzheimer's and Parkinson's, but there are no other (known) neurological disorders in our family history.
Just remember that everyone is different in how the same conditions can react to each individuals capability to absorb certain symptoms. You seem to have an awesome attitude, and many talents. Thank you for sharing this, and try not to worry too much...to soon. You have a great many other things to deal with in life, lol...just like most of us. Try not to allow this one to take the front seat...lol, yes?
