Symptoms: Headache, Hypoaesthesia, Hypotonia, Impaired driving ability, Injection site hypoaesthesia
Clinical narrative: I was administered the Pfizer Booster approximately at 15:20 on my left arm, I was given a timer with 30 min. Sometime during that period I felt a slight numbness on the injection site that radiated all the way down to the wrist (top portion of the arm only), but I disregarded it due to be though to be related to the needle size since they used the drawing needle for administration. I left the clinic with no other symptoms and walked to my car where I took (2) 500mg Tylenol since I did experience fever, flu like symptom and headaches with the second dose (symptoms lasted 3 days and the headache about 10 days post 2nd shot -I did not report these at that time). I left the parking structure and within 5 minutes I began to feel a pulsating sensation on the outer-upper-left side of my left calf (2.5-3inches below the back of the knee), increasing numbing sensation on the arm and mild lightheadedness. At 15:55, I pulled over and ate a mini kind bar, drank some water and walked around for a few minutes in case symptoms were to be r/t hypoglycemia and cramping. I resumed driving at 16:00 but symptoms got progressively worse with severe left calf pulsation on the same area, calf tightness with now a new burning sensation on the outer side of the left heel (below the ankle bone) and moderate dizziness. At 16:05 my arm and legs became extremely heavy, I could feel my heart pounding out of chest and a systemic burning sensation of blood rushing down my lower extremities (the burning can be described as similar to that of medication being injected into the injection site however this was felt like my blood was burning through my veins as it traveled down), I became overwhelmingly dizzy and nauseous, my vision became hazy and finally my arms and legs went completely limp. I managed to stop the vehicle; my coordination was poor (I took approx. 3 minutes to unlock my phone to call for assistant). It took 9 min for help to arrive, I was given oral fluids in the form of water and sugary drinks and applied cold compress to back of my head and forehead. At 16:47 I was finally feeling well enough to leave however still moderately dizzy. The dizziness remained for 3 days, as of today (1/14/2022) I am still experiencing orthostatic hypotension and tachycardia. My reaction has later been diagnosed as a Near Syncope. For the 2 days following the booster administration I experienced moderate to severe headaches and fever ranging between 102.7-103.1 that would not go lower than 102 with medication. The third day my temperature remained around 100.9-101.1 and the headache from mild to moderate.  Footnote: Vaccine Administration time is reported based on appointment time; actual administration time might have range between 2-5 minutes after. All other times have been abstracted from my own cell records so accuracy of times can be considered extremely accurate.  I have not been able to schedule a primary physician appointment due to the high volume of patients however I did speak with 2 providers that I personally know following the event and they both agree on the near syncope diagnosis. My primary physician appointment at pcp is scheduled for 01/28/2022.
