Has anyone had a reaction to the second Co-vid vaccine? I had a PM adjustment on Friday, turning on my Rate Respnse and lowering my pulse to 50 at night and 60 during the day. Saturday I had my second Co-vid vaccine. Since both, I have had a light headed feeling. My BP is 103/73 and my pulse is 80 sitting here at the computer. I did run a fever of 101 over the weekend and I know that was due to the vaccine. I tried a 2 mile walk yesterday and at the 1 mile point my pulse was 60 and my oxygen was 99%. As we came home, my pulse was 115 and Ox 94%. Does it take a while to adjust to adjustments or are they immediate relief? My EP is on spring break until Monday and I'm not sure if this is still vaccine related or if I just have to give it time.
