After drinking night before woke up with numbness in lower lip. I'm presently on my menstrual cycle
Hello,
I'll assume you were drinking alcohol of some kind. Alcohol consumption often brings about low blood sugar levels in the morning. This is true for someone who is diabetic and not diabetic. The low blood glucose levels often bring about tingling sensations throughout the body including the lips. Your lips are very sensitive to this. I doubt you lip tingling had anything to do with your period. If you experience it again, make sure to take in some sugar to bring you blood sugar levels up and the tingling should go away. Try some orange juice, whole fruit or something else sweet like oatmeal and brown sugar.
