Weakness continues

Weakness is a strange thing after a while. I still find myself wondering if the source of all of my weakness is NA.  It fluctuates a bit from time to time but is always there at this point.  Yesterday seemed to be a peak in the weak category as I found it almost impossible without extreme effort, to stand from a seated position.  Shaking and straining all the way, I was able to stand.  Does that sound like anything you read about on NA/PTS sites?  Not really. Weakness is a part of this, but how much is NA/PTS related is still not nailed down for me.  What else could it be?

I still go back to the possibility that part of this weakness could be related to Myasthenia Gravis. But I know that what I feel is not text book for MG either.  Sure, I have had double and blurred vision, particularly prior to my shoulder issue in 2006. But when I see how those symptoms relate to MG sufferers, my eye issues seem small by comparison.  My eyes when tested, do not droop, and do not seem to suggest to doctors that MG could be an issue. But, 20 minutes into reading can make my eyelids shut down, and vision go double. 

I see where MG can present as leg weakness impacting ability to stay standing, and that does sound like me.  I start a task that has me bent over at the waist and within minutes, I can feel my back not supporting me, and if I push, I have to get down before I fall down.  It could be NA, but also MG?  Who knows? 

When I am able to do sit-ups, and I pause for a minute and try to do more, it does not happen.  The muscles just do not want to work again that quickly.  Is that more MG than NA?  I wish I knew.
