Patient received her Covid 19 booster on August 31, 2024. On Wednesday, September 4, 2024, she lost sight and fainted at school toward the end of the school day. She described not being able to think clearly and everything going dark. I took her to the pediatrician to be checked and no clear diagnosis was made. She continued to experience extreme dizzy spells brought on my changing positions and sometimes without any trigger. We saw two cardiologists over the course of several weeks while the symptoms continued. She is a competitive swimmer and was having symptoms in the water as well. All other causes were ruled out (no infections, no illness, no ear issues, etc.). Dr was able to determine that she was experiencing positional syncope and her blood pressure was fluctuating as well as her rate. She was diagnosed with autonomic dysfunction with POTS and syncope related to the Covid vaccine.
