I understand. And yes. It would be exceedingly rare for twitches like yours to be found in ***.
If you ask him, he'll probably just ask you to do what I just told you. He can't be anymore certain than you without an EMG. Listen to me though, I know more about this disease than probably 80% of general practitioners (as it is a rare disease and not really in their field to worry about as they'll probably never see a case in potentially their entire career) and 99% of the community here (exceptions being ShawnW and Pan, likely a few I don't know too). You do not have any clinical sign of bulbar ***. No atrophy, infrequent twitching, wrong age-group, no weakness. You are fine. At this point you should literally be more afraid of being struck by lightning.
THIS is the rabbit-hole you NEVER want to go down (I know, I'm shouting at you from the bottom). I believe that THIS disease IS the pinnacle of Health Anxiety. Vague symptoms. Multiple presentations. Uncertain, but bad outcome. *** is the disease of the unknown. And that is really what motivates HA phobias. Not knowing.
MS and *** prey on the same symptomizations as hypochondriasis. This makes them extremely potent fears. MS can cause electrical feelings throughout the hands, twitching, paresthesia. Not only can it, it often does. These same things are common in anxiety. *** can cause twitching; also common in anxiety.
