Several years back, our family got a bad bad upper respiratory flu or virus or something. One member coughed so hard they pulled something in their chest area, and said it felt like a broken rib woild likely feel everytime they sneezed or coughed after that. Thry were in agony. I ended up In hospital and having to be on a nebulizer, which helped calm it down a bit, but whatever that sickness was, it lasted several weeks, nearly everyone In town hot it too.it really knocked folks for a loop. It was in the 90’s, hope to never get another one like that one, it was awful. Not being able to breath fully is a scary thing, the nebulizer, was a godsend.
Nebulizer saved my Mom from Covid. She almost died.
