Help, is this ALS...

I started complaining about leg fatigue in August 2015. After being referred to a vein doctor, who cauterized several veins, the fatigue, or weakness as I call it today, returned within a few short weeks. By February, 2016, I went back to my primary care doctor who said that we might be looking at ALS, which of course freaked me out. As such, I started researching different websites, including the ALS Foundation, which led me to the Mayo Clinic in Scottsdale, AZ. In April, 2016, the doctors performed a series of tests, which included an EMG. As you all know, only doctors are allowed to administer the test, so that gave me a chance to ask questions. Long story short, he did find abnormalities in both of my calves, but stated he was unable to label it and felt we were looking at something in its early, early, early stages. Returning to my primary care doctor I was referred to another neurologist that performed a second EMG (November, 2016) who also reported the same results, except they worsened. I can feel the same weakness in my arms now. It is getting difficult to hold a plate or my cell phone for more than 10-15 minutes. My gait is unstable. I hold on to walls or furniture for balance. I have noticed muscle atrophy in my calves. I am unable to lift myself from a seated position without using my arms, at least until last night when I required the full assistance of my family to help me stand. All of the tests performed keep coming back negative, except the EMG, which again, reports a declining condition. I even began aquatic physical therapy in early November, 2016, and a few days ago my PT said my symptoms were actually worse than when I started. The muscle biopsy, blood draws and MRIs did not reveal any related muscle diseases. I also learned that a muscle biopsy cannot detect ALS, of course, that was after the biopsy. Ugh! I will be seeing a Rheumatologist in mid-February (2017) for additional testing. Apparently, they can test for even rarer diseases that neurologist cannot. While my doctors are reluctant to classify this as ASL, my primary care told me that was because it would be considered a pre-existing condition, and they do not want me to have that burden; I am convinced that I have ALS, and time is no longer on my side. Help, what are your thoughts?
