On 16-Jan-2021, Heart rate: 120 High. On 16-Jan-2021, Magnetic resonance imaging: normal normal. On 17-Jan-2021, Blood pressure measurement: 190/140 High. On 17-Jan-2021, Computerised tomogram: ruled out stroke normal. On an unknown date, Blood pressure measurement: 192/144 High.     The action taken with mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) was unknown.   For mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular), the reporter considered FACIAL PARALYSIS (Left side of face cured up/ left side of my face was drooping, could not smile/ happened again in the ER around 1:15 AM so i was admitted), HEADACHE (Terrible headache/ massive headache/ headache around back of head persisted), DYSTONIA (body contracted again, started in calves and feet and hands, went into neck and face), TETANY (full body tetany), HYPERTENSION (elevated BP persisted), DYSTONIA (Could be a Tetany or dystonic reaction to the vaccine due to timing of everything/ Muscless tightened all over body/ within minutes after vaccination hands/ feet/ legs contracted/ curled up), LOSS OF CONSCIOUSNESS (passed out immediately following vaccine), HYPERTENSION (Blood pressure was still high pulse was high 120/ BP went sky high (196/148)/ BP remained high), TETANY (Could be a Tetany or dystonic reaction to the vaccine due to timing of everything), PAIN (Whole body hurt/ very sore body) and LUMBAR PUNCTURE (lumbar puncture relieved excess CSF and reduced pressure) to be possibly related. No further causality assessments were provided for HEMIPLEGIA (Couldn't move left side), SYNCOPE (Fainted when she got the shot), TINNITUS (Ringing in ears), HYPERVENTILATION (Hyperventilation syndrome), DYSPNOEA (Shortness of breath), DIZZINESS (Sometimes dizzy) and FATIGUE (Fatigue).    Treatment medication included: Injections of Benadryl and IV Benadryl en route to hospital, Ibuprofen daily as needed and a shot of Toradol.
