Wisdom teeth pulled and sinus problems following

Hello, I had my left top and bottom wisdom teeth pulled about two years ago. Since then I get this sinus or mucus draining into my ear canal. I get this when I am exercising, singing or cold. It drives me crazy. Are the two related? I have tried Mucinex, Silver something ear drops from the healthfood store. It doesn't hurt but bugs the heck out of me!
Help!
