Is it normal for my face to hurt three weeks after jaw surgery? Is it possible to be an effect due to an emergency travel?

Last week my family got the news that one of my cousins lost his battle with cystic fibrosis. We immediately packed up and got on a plane to come for his funeral. However it slipped my mind that I should've called my surgeon first asking if it was okay until a few days ago. The skin under my eyes feel sore and I have no idea what the reason is. I finished all necessary medications that they gave me before coming.
