It is more of a fatigue thing with MCTD. I have been to PT for all the good exercises and balance training and I keep those going. I am 71 this year, and I certainly have noticed the increased need for maintenance of strength! I appreciate your concern...;o)

I was blacking out for 10-12 seconds, increasingly frequently, for over two years. Specialist discovered my brain had shrunk away from the inside of my skull left parietal area. EEG and MRI did it! Third med we tried did it. Dx: drug resistant epilepsy. Good luck. Find a teaching neurologist!
