Since February my resting heart rate has dropped about 20 beats per minute. I have also started having heart palpitations. I’ve had chest X-rays, echo, bloodwork, and EKGs. Nothing shows up. Now, my blood pressure is starting to become super low (89/50). I’m getting dizzy spells and a stabbing pain in my throat. I’m super tired all the time and generally feel ill and nauseous. I’ve had a CT of my brain, too. It showed no masses. My white blood cell count is low, but that’s it. All these symptoms started the day after my first COVID vaccine. Anyone experiencing anything similar?
