I cannot give you a clinical diagnosis over the internet
if it is bulbar ONSET als, then your only symptom is the difficulty swallowing postnasal drip - this is then unlikely
your EMG results can be consistent with an L5/S1 radiculopathy (pinched nerve roots)
Fasciculations in the absence of muscle weakness or wasting is unlikely to be ALS. Also, benign fasciculations are more likely to be widespread from onset, as you describe
In any case, as time is one of the best diagnostic tools of the neurologist, a repeat EMG in 6 months will hopefully confirm or refute the diagnosis.
Good luck
HI! Check out the Benign Fasculations web site at www.AboutBFS.com. It is a wonderful support site for BFSer's. Your symptoms mirror those of other BFSer's. I don't think you have ALS and this website and the people who use it will provide lots of knowledge and comfort to support this. Relax...your neuro is on target! Take care!
