I am in the preliminary stages of neuro visits to determine why I am biting my tongue, cheek, lips I mean no disrespect, but I find your posts scare people and contain inaccurate information. Eg:your reply to someone who bites their tongue 'Def UMN'. Jaw jerk, increased startle: 'Definitely UMN'. Hyperreflexia does not equal increased starle. Hyperreflexia is determined by tests by a neuro for Babinsky's and Hoffman's or hyper jaw jerk. Tongue biting could have many causes. Not all so-called bulbar signs are UMN. Please keep this is mind. You are causing many members undo grief. Do not respond to queries with 'Yup. That is DEFINTELY UMN'. You do not know this. No evidence to substantiate such claims. Sometimes a headache is a headche, not a brain tumour..."When you hear galloping, think horses not zebras". I really needed to tell you this. I've read many of your posts and they are unduly negative and fear-inducing, which I sincerely hope is not your intent.
