LONG covid? COVID Pneumonia?

I had Covid back in November 2020 and still struggle to breathe walking up the hill to my mailbox and to the house from my shop uphill. I finally got most of my taste and smell back this year and could probably get my breathing back but my bad knees prevent me from taking my 2-3 mile daily walks. My Doctor knows am against Covid vaccines and doesn’t push it but highly recommended I get my very first Pneumonia shot because of my heart attack in 2000 which I lost 1/4 of my heart. I wish you luck getting your health back and you are in my prayers.
