Some spit and tape should do you fine.
That is something you just need to live with. Many times, people think they have concussions when they really do not. I wouldn't go see a doctor. What could he do for you? All he would say is take some Advil (no s***, wow doctors are smart). If you do go to the doctor, make sure you get some of their good stuff, I'm talking hospital strength stuff. That s*** works wonders.
