It was through the roof/Blood pressure was high and she was concerned she would have a stroke; Muscle soreness; Arm soreness; This is a spontaneous report from a contactable healthcare professional (physical therapist). A 57-year-old female patient received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, lot number and expiry date not reported), intramuscular on the left arm on 21Dec2020 08:15 at a single dose for COVID-19 immunisation; and sumatriptan from 25Dec2020 to an unspecified date at unknown dose and frequency (standard unknown dose/ She only gets 9 pills a month) for migraine. Medical history included ongoing migraine, obesity (She would say she was kind of obese), coeliac disease (She had Celiac disease and cannot eat gluten which was diagnosed since she was 4), chronic back pain (this was diagnosed a couple of years before she took the COVID vaccine), spinal stenosis (this was diagnosed a couple of years before she took the COVID vaccine), and pain (she took hydrocodone for pain but did not take any that day).  Concomitant medication included hydrocodone for pain. Prior Vaccinations (within 4 weeks) and events following prior vaccinations were none. The patient had the vaccine on 21Dec2020, and she got sick on Christmas day. She was vomiting at 14:00 and did not know if it was a side effect or not.  She did have arm soreness muscle soreness at 15:00, that evening and the next day too. She normally gets a migraine once a month. She does not normally throw up with a headache though. The vomiting started when she threw up twice on 25Dec2020, then once on morning of 26Dec2020.  She also had very high blood pressure. It was through the roof.  She did not know if that was related to drug for migraine or vaccine. She also had the headache at 14:00 the whole time. She believed she threw up before she took Sumatriptan. The muscles got rigid and tight in her neck and she doesn't think she took it. She threw up and then she took it. She did not have a lot or expiration. There was no ER nor physician's office required. She would have it if her car was not buried in snow. Her blood pressure was high and she was concerned she would have a stroke. It was usually around 110/70 and was always very low usually. She did not know if it was accurate, but it was 165/124 at one point and she did know her pulse was accurate. She did not provide her pulse rate. She did not know if she was throwing up because her blood pressure was high and did not know if blood  pressure was high because of Sumatriptan. She only gets 9 pills a month. She did not know if high blood pressure was one of the side effects. It was not a real safe medication to take once a day. She only took it once a month and only once that day. She had never thrown up with  migraines before and was just concerned. She doesn't usually take her blood pressure and doesn't know if the Sumatriptan always makes it go up or not. She doesn't know if she had the flu bug or not. The action taken in response to the events for bnt162b2 was not applicable, while for sumatriptan was unknown. Clinical outcome of sickness and influenza was unknown, for headache was recovered on 27Dec2020, while for the other events was recovering.
