@rmc1021 and @mbryant1380 You are not alone with the symptoms you describe. Reads very similar to mine that began shortly after my first (and last Moderna booster!) in November 2021. The sensations I have/had are unique and difficult to describe exactly. Feels like dizzy but not exactly, feels like dropping on a roller coater but not exactly, feels like light headedness but not exactly, when I stand/stood still I sense a rocking sensation. At not time have I fallen and I do have good balance. The only time my Wife and I tested positive for COVID in July 2022. I knew something was wrong and went to my GP in January 2022, he threw every test in the book at me and my journey of "what its not" began here in Charleston SC. Long story short advocated/pushed for myself and ended up at Mayo Rochester August 2023. Executed the Mayo program and now feel better and hoping Long COVID becomes a memory. mbryant1380 You are not alone with the symptoms you describe.

Executed the Mayo program and now feel better (notice in some of my descriptions I use past/present tense and hoping Long COVID becomes a memory. I wish you well in your recovery. Highly recommend you take "the journey of what its not" with your local providers and then if needed find your way to Mayo Rochester for their program. It has worked for me.
