This 44-year-old female patient received BNT162B2 (Pfizer-BioNTech COVID-19 mRNA vaccine) (Lot number: EK5730), first dose, intramuscularly in the left arm on an unspecified date in Dec2020 at 08:45 (at the age of 44-years-old) as a single dose for COVID-19 vaccination. Medical history included peripheral neuropathy (genetic and progressive) from an unknown date and unknown if ongoing, Charcot-Marie-Tooth disease from an unknown date and unknown if ongoing and amoxicillin allergy from an unknown date and unknown if ongoing. Concomitant medication included minerals nos, quercetin, thioctic acid, vitamins nos (EMERGEN-C) and sambucus nigra extract (SAMBUCOL). The patient previously received the flu shot via an unspecified route of administration on an unspecified date in Oct2020 as a single dose for immunization and experienced headache/ pain over left eye and some sensation change in her left cheek. Prior to the vaccination, the patient was not diagnosed with COVID-19. The patient did not receive any other vaccines within four weeks prior to the vaccination. The patient was not pregnant at the time of vaccination. On an unspecified date in Dec2020 at 08:45, the patient experienced new nerve or neurological symptoms have all occurred on the left side of her body, which is the side she got her injection. Hours after the vaccine, she experienced a headache/ pain over her left eye and some sensation change in her left cheek. This also occurred after her Flu shot in October as well, but for the first time (has gotten Flu shot before without this response). The patient expected a headache and arm tenderness as she had been informed ahead of time. She felt functional though the rest of the day, with some chills in the evening. Day 2 was the most challenging day, with all the symptoms (mostly expected)-headache, muscle aches, fatigue, mild fever, chills, but also hot flashes, nausea, to the point of throwing up (after a long nap). The vomiting only occurred twice, and nausea improved there after. However, she was trembling uncontrollably for a bit through this so she napped much of that day. The patient also had muscle spasm in her left leg and eye periodically (and still). Nerve pain still as well. The adverse events resulted in a doctor or healthcare profession office/clinic visit. No therapeutic measures were taken as a result of the events. The clinical outcomes of the new nerve or neurological symptoms have all occurred on the left side of her body, headache, pain over her left eye, some sensation change in her left cheek, chills, muscle aches, fatigue, mild fever, hot flashes, nausea, vomiting, trembling uncontrollably for a bit through this and muscle spasm in her left leg were resolving. The clinical outcomes of the muscle spasm in her eye periodically and nerve pain were not resolved. It was also reported that since the vaccination, the patient had not been tested for COVID-19.
