The EMG signature of ALS fasciculations has a different frequency range than "benign" fasciculations, so your neurologist would know what to look in the EMG. You might stop by the nearest university with a medical school and get a copy of this article:
LONG-TERM FOLLOW-UP OF 121 PATIENTS WITH BENIGN FASCICULATIONS
BLEXRUD MD, WINDEBANK AJ, DAUBE JR
ANNALS OF NEUROLOGY

Also, I had an EMG with normal readings done by my neurologist. Normal blood tests as well. He says my EMG showed twitches, but they looked normal (benign?).
Without seeing you personally, I can't make an accurate diagnostic opinion. It's not uncommon for younger people (30s or younger) to have generally brisk reflexes. The question is, how brisk is brisk? ALso, muslce weakness and wasting (which is well known to be a part of ALS) was not mentioned in your post. Hopefully, it will just turn out to be something that isn't serious like benign fasciculation syndrome. But if everything is getting worse or prominent you should consider getting an EMG for further evaluation. Routine lab work should also be done to look at thyroid, muscle proteins like CK and aldolase, and electrolytes. In the meantime, over the counter magnesium supplements in recommended doses as well as soda water *which contains quinine, a substance that may have cardiac side effects when taken as a pill in predisposed individuals, but is ok in the amount of soda water* can be helpful for symptomatic relief. Good luck
