i and others with hyper jaw reflexes have spasms.
i get pain ,stiffness and weakness in my lower facial muscles/jaw.
the spasms have been so bad sometimes they physically distort my mouth,usually the right side.
the jaw slamming shut is a completely involintary abnormal distressing symptom.
many times i have caused serious injury to my tongue if it gets in the way,so have many others i know.
my lower facial muscles and chin area have dropped so much this past year.
physically my face has changed and i have uneven amounts of muscle loss.
the umn problems have effected my swallowing,chewing,throat muscles causing a strangled sesnsation and speech ,also tongue problems.
