This year I believe there was a really different respiratory issue that many people I know acquired.
This respiratory issue started with extremely thick sinus blockage then slowly moved into the lungs. Through out the time people would occasionally experience fever and or chills. Once it moved into the chest it stayed there for months.
I went to the doctor twice over it. Z Pack did the best with mullein tea, zinc, and vitamin C. Not sure if it helped but last week I started a maintenance round of Fenbendazole.
