I now know that this is called hyperreflexia, but before i always thought it would good to be super jumpy!, i thought it always meant you were fast ;]
But now it is too seems like another symptom associated with MS. I am now getting scared of it being bulbar onset als! Because of the scalloped shaped tongue (had for years), hyperreflexia, and throat clearing. Yay more worries

How do doctors figure out the difference between a normal response and hyperreflexia and associate it with UMN? What if one person is just really reflexive? Or is that not the case and hyperreflexia is always clinical of something else? For others with MS, do you have very brisk reflexes and are they symmetrical or asymmetrical? I am going to contact a neuro for a complete neuro exam and emg work-up.
