I was on the phone and my lips and tongue started to tingle and my lips are still doing it. All I've eaten today is my normal cereal (hours ago) and some cheddar cheese (right before it started happening). It isn't new cheese (i.e. I ate from the package on other days) but it isn't expired.
What the heck could this be? I probably haven't had enough to drink today...could deydration cause it?
