Possible Sinus Infection- Kinda Gross

I am periodically smelling a foul odor that appears to be coming from my nasal passages. At first, I thought that it was my mucus, but my husband can't smell it on tissues.

Of course, I Googled it and there were a bunch of possibilities.

• Sinus Infection
• Nasal Cancer
• Cryptic tonsillitis

The worst would be cancer. The best, an infection treated with antibiotics. I'm headed to the doctor's office at 4 to find out what they say.
