Hello SandySometimes it can happen that an SD patient (that is, laryngeal dystonia) can experience the dystonia spreading to the muscles around the mouth/jaw. In this case it is referred to as "oromandibular dystonia". I hope that doesn't turn out to be the case with you - it can make eating very difficult for example.

It could also be benign fasciculations, the kind of twitching you get under stress sometimes. I've had them in the eyes, arms and legs. I've done a Net search and most info says it's a common (but annoying) thing.Try drinking some Tonic Water (with quinine in it)...it seems to help the muscles.
