I woke up this morning with a really sore throat, sinuses, and a sinus headache. I used my neti pot and it broke something loose that I had no choice but to swallow. Since yesterday, I have noticed an occasional foul smell, but after I knocked whatever that was loose this morning, it has increased dramatically. Went to the immediate care and it s not a sinus infection. The smell is so awful! I have been using my sinus rinse and putting lavender oil under my nose but that only masks the smell for so long... Help!
