Good day, I hope that I haven't been bothering you. It's so refreshing to have someone to talk to that knows what I'm going through. Our symptoms sound alike. My symptoms started a few years before diagnosis as well. They thought that I had knee problems from work and went as far as surgery on both knees to see what was going on.When they couldn't find anything they said it was petalla femoral syndrom,a wasting of muscles around the knee. Then the atrophy of the entire leg began. Still walking,but have bad foot drop, stumble and trip alot. The other leg is starting to show signs now. After a good day of being on my feet it feels like I ran a marathon. It's tough because my wife works from 5-10 at night so I still have to suck it up and deal with chores and the kids, when some nights all I want to do is lay there and rest. Again sorry if I'm bothering you with all this,but it is a relief to talk about struggles with someone that understands. Take care, have a wonderful day.
