Non-scents

I seem to have totally lost my sense of smell. I first noticed this a couple nights ago, when I couldn't smell the Badger Balm I was using on my sore nose, but I thought it was just that the Balm was old and had lost it's scent. It was only tonight that I realized I couldn't smell anything. I stuck my nose in a box of Altoids. Nothing. I tried smelling a bottle of Valerian, an herb with a very... penetrating... aroma. Nothing. I even tried Garlic. Nothing!

My nose isn't stuffy or anything, I can breathe just fine. I hope this is just temporary.
