Hi Shocktempo. I had a very similar event. On May 4th 2021 I have my second vaccine shot. The next day I was in afib for the very first time of my life. I have had 4 afib events since the shot. It’s been six months since my last event. The first six months was absolutely terrible. I had no energy and my stomach went totally sideways on me too. Now I have gastritis and if I eat poorly then the gastritis gets bad and I end up with palpitations. All my tests on my heart have come back perfectly normal. I am 60 years old now and I am still recovering from whatever the vaccine did to me. I am a very active and healthy person all my life. Now I’m struggling to get back to my normal life style. I wish you luck on your recovery.
