This cough won’t go away!

I meant to call my doctor but he closes at 4pm and by the time I remember literally anything it’s 4pm.

About a week and a half ago I ended up in the hospital because I couldn’t breathe and I was very VERY sick. I had a COVID test, actually i had TWO Covid test which were both negative. I had my white blood cell counted. I actually went to an urgent care and a hospital, so two doctors saw me. They did chest X-rays (and yes it’s all in my chest I literally feel the thick mucus breaking up and coming out of my chest but I have yet to have a runny snotty nose)

What it came down to was that the doctor suspected a viral respiratory infection. I was prescribed cough medicine, and it helped. But this cough won’t go away, I’m still having trouble breathing even though I’m on 20mg prednisone and nebulizer treatments with pulmicort (an inhaled steriod)

And yes, I have definitely gotten better. I went to the hospital because I felt like I had cement clogging up my lungs and I was really not okay and it was scary. I’m functional now.. but this awful nasty cough WONT go away. I am still coughing up phlem and it’s been weeks. Literal weeks😭 I want to go back to being my normal healthy self for the love of everything holy. Do you think this is normal? Or should I bother my doctor about it again?
