Hello Joel
I took a look at the EMG and you do not currently have any active denervation in any muscle that was tested. Active denervation means that your nerves are actively being damaged and they then lose contact (i.e. denervate) with the muscles they control. The normal (N) indication in the columns under PSW and fibs confirms that.
You do have a few 1+ values under the fasics column, which could or could not mean anything. The good news is that none were found in your tongue, which is where your symptoms stem.
There are also a few 1+ and 2+ values under the Amp column. Amp is short for amplitude . . . the amplitude of something called the motor unit action potential (MUAP). There is a measure of the electrical activity in groups of muscle cells called motor units. If the measured value is bigger in amplitude, the 1+ or 2+ or 3+ etc. will be indicated (the larger the value the bigger the amplitude). These larger values indicate that damage to the nerve controlling the particular muscle occurred (which led to denervation) at some point in your life but then new contact was made. This is known as reinnervation. Therefore, you have reinnervation in those muscles with the 1+ or 2+ values.
You also have some 1+ values in the Poly column. This indicates instability of the nerve, which can happen for a lot of different reasons (early denervation, inflammation, etc.).
Bottom line: that EMG is inconclusive and I'm sure they will want to give you another one in 3 to 6 months. As of right now, given your story and that EMG, you could not be given an ALS diagnosis; it just doesn't add-up (there are too many odd things that are happening, namely your ability to recover functionality).
I wish I could be of more help but I would insist that you keep me updated because I want to try to continue to help. In the meantime, ask your neuro to give you his/her impression of the EMG and make sure he/she makes it clear to you.
