I would not be too concerned. ALS usually manifests with fasciculations in multiple muscles, and since you are only experiencing infrequent fasciculations in a single location a neurologist would likely just follow your situation for several months to see if there are any changes. If you do not have any muscle weakness or atrophy that would also be a good sign. It could be nothing, or it could be something innocuous like BFS.

While you shouldn't ignore it, I doubt that you have reason to panic.

I have to have a three limb EMG on Feb. 11 since I am having nonstop fasciculations in several muscle groups and have been having sporadic facsiculations in various muscles. I'm crossing my fingers that it is BFS rather than ALS. All other causes have been ruled out is it coming done to one or the other.

Good Luck!
