The part about EMGs is that they can detect denervation (loss of axon) and re-innervation (growth of new axon) caused by ALS. This is a big reason they allow the EMG tests to be part of the diagnosis. The criteria originally excluded anything outside of the clinical exam, but enough evidence has proven that this is a strong diagnostic tool. Other conditions can cause the damage as well, and that is why they must rule out everything else before they can rule in ALS. MND is an umbrella for several related conditions, like PLS. The EMG's you have had should start showing de-nervation (fibrillations/fasciculations). They should also start demonstrating long MUP's which indicate re-innervation. Without this, you can be sure it is not MND. EMG diagnostics can be complex, and most laypersons have little idea what all this means, so I tried to simplify it so you get a little understanding.
BFS will not show denervation or re-innervation. This is likely what the tech saw when he said BFS in your 2nd EMG. Still, the accumulation of symptoms should put a red flag on your medical file. They need to find out what is causing this condition. You are your best advocate at this point. If they tell you it is not ALS/MND, then your next reply should be asking what it IS, not what it is not.
Mattew and the others also gave you a good suggestion. This is a very stressful time in your life, and it sounds like you are worrying beyond imagination into some very bad places. Fear is natural and that is where it takes you. Speak to a psych and tell them what you are going through. I do not think you are crazy, but I do know that they can give you something to take the edge off of your stress.
