Thanks for your response. I was a performing dancer and yogi and have been exercising and physically active for most of my life! Since December 2022, my life has also changed dramatically. Right now I am waiting to hear from the Scripps Long Covid Clinic. My blood work came out positive for Covid infection, so they know for sure I am post Covid. They are supposed to have a staff of every specialty working at that site, so I hope to find some very competent professionals. Right now I am working with my cardiologist. I will be on a heart monitor for 2 weeks. I do feel that this problem I am having is a result of being post Covid.
