nasopharynx & stubborn mucous?
I'm going out of my mind. I had a sinus/cold/flu-thing. One week of the usual sniffing, coughing, aching and then (I thought) it was over. Post-nasal drip imperceptible. Yet I feel like I have mucous sitting above my soft-palate. I'm guessing the nasopharynx. I can make the kind of pressure that usually clears mucous so it can be swallowed (ok so not appealing but effective). The insane part is I feel like something is lifting off but immediately I'm right back where I started. Can't swallow it. Can't cough it out. The constant unnatural sensation has me out of my mind. Nurse Practitioner swabbed- not Strep. I rinse my sinuses with a Neti Pot. I gargle with saline. I do a hard swallow instead of coughing to reduce irritation. NP put me on antibiotic but I'm desperate about this "phantom" mucous, this swollen feeling. As I write this it's been a full week of "torture". My only relief is when I am asleep.
