What is this pain in the upper part of my gums just before cheek connects?

Get it checked. Pain is your body's way of telling you there is a problem. In the area of your mouth you indicate, pain could come from different causes, including infected tooth/teeth, infected gums, injury, or allergy. The only way to know is to see your dentist and get it checked out. Good luck!
