I had Moderna caused cardiac autonomic neuropathy (CAN~no treatment given supposedly eight years left to live) along with small fiber neuropathy. I wish I would have never taken the two shots. The cardiologist said they knew from the beginning that it caused CAN. I have bradycardia/tachycardia and my blood pressure either gets too high, then drops really low. It can’t make up it’s mine what it wants to do. It’s a very scary experience. My blood pressure was high for two weeks 150/100 then the cardiologist put me on blood pressure meds and my blood pressure got too low was in the hospital then it went back to normal. It was very scary to go through. I was so sick and nauseous from the roller coaster ride.
