They did an MRI and afterward, said her blood pressure was 200 over 100 something. They didn't tell her. Thought she was going to pop a gasket. Was bruised for the next 4 months. Personally, she did not go back and take anything else. Was quite concerned those kinds of things could be happening with the vaccinations. They didn't count the fact that she was female, and they forgot to account that in her immune system. Caller was not taking any more vaccines, ever, after that. Knew they did some kind of reporting, came from Pfizer at the time when she was at the hospital. Didn't tell who called but did not return call because she was cautious about it being a scam call. Kind of glad she got this on file. Reporter details: Was a neuromuscular therapist, always taking into account drugs, when working on anybody's body.

Height: Probably about 5, 7 and a half. Primary / Prescribing Healthcare Professional Info: stated as ok to contact her but, she was so overwhelmed right then. Full contact details unknown. Did not see any doctors during that Covid time because they were very careful about who they saw, other than who went to ER. Was bruising quite badly. Clarified this is caller's first-time reporting this with Pfizer. Guesses this would have been when she went to hospital when she had that second vaccination. She thought the hospital reached out to Pfizer because she got a call from somebody identifying it as from Pfizer and some kind of reference number was given. Reference number: Unknown. Didn't know where it came from, there was such scamming. Bruising: 3 days after second dose. The first one was first or second week May2020. Second one came first week Jun2020.
