Began to lift in the third week and my breathing normallized after a few months. In the meantime, my heart checked out OK.
Post nasal drip didn't completely lift until I used the Iword a month ago. It was one hour and like someone pulled the drain stopper on a utility sink.
Sounds like the same i had. My wife and i eat a lot of cheese and fruit. Mine lasted 3 to 4 days. The wife about two weeks. Our son inlaw traveled to china on business just before Christmas 2019. our entire family had flu like something. We think it was kungflu.
