Well, that's not good.

The cold has returned with a vengeance, and now feels like an insane head cold. And the worst part? I ended up with Tinnitus. I have a horrid roaring sound in my right ear - like a fridge buzzing - and I wasn't prepared for how depressed that would make me. I've felt very down, for a day or two. I'm bashing the sudafed, to help the Sinus pain - hopefully that will help.
