Me too. After a second dose Pfizer vaccination, I had shaking sensation in my nerves, stiffness in every joint in my body, and weak heart rate with shortness of breath. I got better but I believe I was permanently damaged. I had an EKG a few months later, showing I now have bradycardia. I can’t prove that I didn’t have bradycardia before and I think I might have in fact, however, something is subtly different.
