Tongue issues

Hi, I’m 19, and recently got an ulcer on my tongue, right on the tip, it’s been here for nearly 2 weeks already. The patch around it seems to have been red, and it feels odd, like, not numb, but not how it normally feels. It reacts every time I eat something, and the skin feels tight. I have lynch syndrome msh2 as well. Am I being dramatic for worrying, or do I need to see the doctor?
