finished eating lunch and rose to wait on a customer. while standing felt a numbness in my lower jaw - mostly left side and I felt uncoordinated in opening my mouth to talk. This lasted for maybe 4 seconds total. I am 51 yr old female, not active lifestyle, desk job, 5'5" and 187#. I currently am taking blood pressure meds - metotoprolol (?prob spelled wrong) What could be wrong with me?
