These grape-sized blobs of I-don’t-know-and-I-didn’t-ask are what kept my sinuses from filling with air. They also kept them from flushing out all the horrible mucus. Thus: infection, pain, poor breathing, infection, gunk, embarrassment, infection, more pain, a box of Kleenex on every flat surface of my home, burning, swelling, infection, pain. Repeat cycle once each month.
