Not bulbar ALS: If you had bulbar ALS, it would be obvious after 4 years. Many folks have these benign fasciculations. The best way I know to stop being preoccupied with trivial non-symptoms is to embrace high-level wellness. You're 28, young enough to be an Olympic champion. Really push your body in your favorite sport and resistance / aerobic training, eat like an athlete, and have a body you truly ENJOY.
