I was dx w/ Amyotrophy and I will give encouragement that in a high number of cases, there is an acute phase. Yes I got weaker as I had muscle wasting in the quads, gluteus maximus and siliac muscles. The exasperation for me was that PT, while did no harm, did not improve strength. My strength is returning slowly. More in tune with nerve regen than PT. Try not to worry about things that have not happened yet. Hopefully you are in an acute-phase that will accelerate the timetable. Make sure your b-12 is over 400, excersize to tolerance, get sleep, if you search for Mitochondrial health and do what you know to do, tests will give you a better idea what you are dealing with. I stayed in a panic for many months so I know how answers are important. Patience is always the shortest when the need is the greatest. Good Luck, Ken in Texas.
