I am the same way about calling the ambulance. I am afraid of the label of hypochondriac. The hospital I live near does not really deal with MS very often and whenever I have had to be in the ER they have no idea what to do with me. I did not know Zanaflex could cause these types of difficulties. I take this medication so I guess I will check out the possibilities of this being a complication. Another great question to add to my doctor’s question list. Thank you.
