Not common: Not common, certainly, but if you are concerned I would not hesitate to be fully evaluated by a neurologist.

There are hereditary spinal muscular atrophy syndromes occurring from young childhood through late adolescence into early 20's, but this would be very unlikely based upon your history. ALS in your 20's would likewise be unusual. Suspect most likely benign fasciculations, but some other diagnoses might be considered. See your primary doctor and discuss if neurology consult is needed.
