Hi @6189. The activity part of covid is sooooooo frustrating. I use to be on my feet 8-10 hrs a day 5 days a week lifting and constantly aerobic. Now a year and half later I am able to carry pitcher of water to water plants and I conserve my energy during day moving from bed to couch to bathroom to refrigerator so I can get to sprinkler in evening. My whole body systems are compromised and yes the blood pressure, heart rate, metabolism . . all over the place. From what most post covid posts appear to share, the battery analogy and really having to listen to our bodies is critical. Feeling fine and able to exert oneself can deplete your energy at cell level which continues this frustrating everchanging unknown territory. I can say my doctor says I was the worst case and I feel fortunate to look back a year and a half and know I am here and grateful pacing with restraint found small improvement of lasting recovery instead of constant setbacks. Hope this helped and know we all wish you a healing journey🌈
