Hitting a wall?
I wanted to report that now, 6 months post PM and 2 weeks post 2nd Covid vaccine, I feel much better. I've done some 2.5 mile hikes around town, with my pulse staying at about 90. While climbing 500 feet, my pulse did get to 150, but then recovered to 90, as I leveled out. My question is, as I am finishing the hike, my pulse comes down to my set 60bpm with my oxygen at 99% and I feel very tired. Is there a wave to the recovery rate that after you have high pulse numbers, does it takes you back down making you feel tired?
