Dealing with Respiratory Illnesses - Any Advice?

Hi. This is my first post. I was just wondering if any of you have been dealing with any respiratory illnesses recently (other than COVID, RSV and Flu-A and Flu-B). I’ve been really sick over the past few weeks, but am consistently testing negative for the above listed illnesses. I’m on my second round of oral steroids and antibiotics. I ended up in the ER yesterday and got 3 breathing treatments and IV steroids. (I also got a prescription for cough medicine.) I know that flare ups can linger for a bit. I’m just wondering if anyone is going through a similar experience and would be willing to share their story. Thanks ❤️
