For about four or five days now, the left side of my head has been in pain. It's one of those incredibly annoying throbbing pains, that turns into a stabbing pain whenever I cough. Every so often, my left tear duct will start streaming tears, and my left nostril will run as well. Even though this is all happening on the left side, both of my eyes are bloodshot. The right side of my head feels completely normal.

I truly hope this is a short-term thing, it's getting to be unbearable.

EDIT: I tried Mucinex to clear my sinuses, but it didn't do a thing.
