The day after my 1. Pfizer 💉, my heart started racing. I thought it was nothing, but two days later, I started having severe stabbing pain and pressure in my chest, with radiation to my left arm. I went to my own doctor, who thought it was stress and anxiety 🧵 #CanWeTalkAboutIt It took five visits to the doctor/ER, before I was admitted to the hospital. I hadn't slept for a week because of the pain. At the hospital, they found thickening of the pericardium and elevated troponin. Perimyocarditis. I stayed for 1 night before I was sent home.
