I’ve had this for 4 going on 5 years now. It’s gotten so bad it wakes me up in the middle of the night. Always happens in the morning.
They just chalked it up to asthma and I do believe I developed that later on from severe acid reflux— but they were never able to explain why the phlegm happened after covid!
It’s every single day for me and I wish I was exaggerating.. the only thing that provided someee kind of relief was a nasal rinse.
Even then it just makes it so that I have less symptoms, over none at all.
It’s even made me develop tonsil stones (I’m 19 and never had before)
