Pericarditis; had a tear in her hip that she had surgically repaired and got a booster set off a flare in her hip; had a tear in her hip that she had surgically repaired and got a booster set off a flare in her hip; mass; This is a spontaneous report received from a contactable reporter(s) (Consumer or other non HCP) from medical information team. The reporter is the patient.  A 70-year-old female patient received BNT162b2, BNT162b2 omi ba.4-5 (BNT162B2, BNT162B2 OMI BA.4-5), as dose number unknown (booster), single (Batch/Lot number: unknown) for covid-19 immunisation. The patient's relevant medical history included: "gout" (unspecified if ongoing), notes: She's guessing the good news is she won't have gout for 3 months; "MS", start date: Aug1998 (ongoing); "Immunosupressed" (unspecified if ongoing), notes: has an underlying condition and is immune suppressed; "tear in her hip" (unspecified if ongoing); "tear in her hip that she had surgically repaired" (not ongoing). The patient's concomitant medications were not reported. Vaccination history included: comirnaty (DOSE 1, SINGLE , Lot#: EL9263), administration date: 25Jan2021, when the patient was 68-year-old, for COVID-19 immunisation, reaction(s): "sore arm", "Did not feel 100 percent but felt ok"; comirnaty (DOSE 2, SINGLE , Lot#: EN6201), administration date: 15Feb2021, when the patient was 68-year-old, for COVID-19 immunisation, reaction(s): "typical sore arm", "did not feel 100 percent"; BNT162b2 (DOSE 3 (BOOSTER), SINGLE , Lot#: FC3184), administration date: 06Sep2021, when the patient was 68-year-old, for COVID-19 immunisation, reaction(s): "typical sore arm"; BNT162b2 (DOSE 3 (BOOSTER), SINGLE , Lot#: FC3184), administration date: 06Sep2021, when the patient was 68--old, for COVID-19 immunisation, reaction(s): "did not feel 100 percent"; BNT162b2 (DOSE 4 (BOOSTER), SINGLE , Lot#: FJ9943), administration date: 14Mar2022, when the patient was 69-year-old, for COVID-19 Immunisation, reaction(s): "very severe site reaction", "it swelled up very significant swelling", "incredible welt". The following information was reported: PERICARDITIS (medically significant), outcome "not recovered"; JOINT INJURY (non-serious), CONDITION AGGRAVATED (non-serious), outcome "unknown" and all described as "had a tear in her hip that she had surgically repaired and got a booster set off a flare in her hip"; MASS (non-serious), outcome "unknown". The event "pericarditis" required physician office visit and emergency room visit. Therapeutic measures were taken as a result of pericarditis.  Clinical course: She was diagnosed with Pericarditis. She knew its been reported in young men and teen boys, that they suffered the same side effects. But from everything she's read, have you seen that reported in other cohorts. When she saw her cardiologist who diagnosed her with that, they hadn't seen it in a patient like her. She had her mass, her neuro hadn't seen it. Caller stated pericarditis started one month after, or three weeks after she received the vaccine. So she was on medication for 3 months. She was on colchicine for 3 months, so she just now kind of passing the first month mark and she was still having symptoms. She was  guessing the good news was she won't have gout for 3 months. It was a gout medicine but that's what they prescribe for pericarditis. She can't be the only woman in the world that had these reactions. That would be one for the medical books. she ended up in the emergency room twice and at a cardiology office to confirm this diagnosis. The cardiologist was obligated to report that. So unless someone reports it there's no way to know how many people were actually having side effects. That's the interesting thing about data, you're reliant on people reporting. For her it was critical that no one else suffers this again. What data was out there that you can trust. She's really informed medically about her own situation, but its hard to make an informed decision without there being good data out there. Her husband in particular has had a few inflammatory responses, not anywhere like this but a hip flare or something. Caller states she's wondering if inflammation is reported after the vaccine. Its a big question for her family. Both her and her husband have both experienced it. She had a tear in her hip that she had surgically repaired and one of vaccines, one of the times she got a booster set off a flare in her hip. Her husband had the same experience with his knees. She was just wondering if it was anecdotal or if that's something there is data on. Knock on wood, neither of her or her husband have had had Covid. It makes you wonder if the side effects are worse than the disease but they really don't want to get it, especially with long Covid.
