I have the exact same experience. Had covid sept of 2021. 3 vaccines.

Phlegm for over two years. I have tried everything. Now, as of last week my ENT suggested my last option is surgery..

The medical community does not know how to deal with long covid.

A large portion of the medical community needs convincing that your individual symptoms are even real… very discouraging.

This is drastically and negatively affecting my life.
