LONG covid? COVID Pneumonia?

I was just in the hospital this week and my lung doctor told me that they are trying to find out about long covid and how to deal with it.... Many people are developing it after covid.....

It's still too new and they haven't gathered enough data on it yet, but are looking into it and how to combat it...
Going on 5 months here.... last chest x-ray tech said " we're seeing alot of it"
