After long day driving through traffic, i ate some food and my heart rate was up to 110 bpm. i also have sharp pain in back left corner inside mouth when moving tongue too much. are these bad signs?

Ans: I think you have to consider what you said. You drove all day. Probably tired and dehydrated. So sedentary not good for the body. Try resting hydrating and get up and then walk around care how you feel then

EKG: I would definitely get at least an electrocardiogram if the symptoms persist. Go to the emergency department if you develop chest pain or shortness of breath.
