I could not sleep at night; I developed frozen shoulder/ pain, non-movement; I developed frozen shoulder/ pain, non-movement; I developed frozen shoulder/ pain, non-movement; This is a spontaneous report received from a contactable reporter(s) (Consumer or other non HCP). The reporter is the patient.  A 52-year-old female patient received BNT162b2 (BNT162B2), on 23Nov2021 as dose 3 (booster), single (Lot number: FH8030) at the age of 51 years, in left arm for covid-19 immunisation. The patient's relevant medical history was not reported. There were no concomitant medications. Vaccination history included: BNT162b2 (Dose: 2, lot number: ER8729), administration date: 15Apr2021, when the patient was 51-year-old, for COVID-19 immunization; BNT162b2 (Dose: 1, Lot number: it is either ER87B0 or it is ER87), administration date: 25Mar2021, when the patient was 51-year-old, for COVID-19 immunization. The following information was reported: PERIARTHRITIS (medically significant), ARTHRALGIA (medically significant), JOINT RANGE OF MOTION DECREASED (medically significant) all with onset Apr2022, outcome "unknown" and all described as "I developed frozen shoulder/ pain, non-movement"; INSOMNIA (non-serious), outcome "unknown", described as "I could not sleep at night". The event "i developed frozen shoulder/ pain, non-movement" required physician office visit. The patient underwent the following laboratory tests and procedures: X-ray: there is no broken bones, nothing. Therapeutic measures were taken as a result of periarthritis, arthralgia, joint range of motion decreased, insomnia. Clinical course: The patient was calling because she received three vaccines from the Pfizer from the start of the pandemic until last year and then after her last booster. She developed frozen shoulder which put her through an orthopedic doctor and physical therapy for almost 11 months now. The reason she was calling was she believed that the Pfizer vaccines mall three of the vaccines that she received, she felt that they attributed to the frozen shoulder. She was young person, physically active, not overweight. She believed that the vaccine caused her shoulder frozen. Apr2022 was when the frozen shoulder started. Pain, non-movement and after three months of pain, "the pain where I could not sleep at night". I went to orthopedic doctor for X-ray and doctor said "there is no broken bones, nothing." The patient went to an orthopedic doctor because of she had 3 months of pain. She did two cortisone shot in her shoulder over a six months period one on the front, waited three months at back of the shoulder with physical therapy. Her shoulder and her arm is at 95% which is great but the reason she was calling is in the last 4 months, she have met about 30 people, these are friends and colleagues across the country, females, males, different ages. They all reported to her that they have frozen shoulder (Further clarifications unknown) and they all have gone to doctors. They all just got the shocking that they are undergoing shoulder pain. The one thing they all have in common was they had three vaccines for COVID multiple times in the same arm that they all got frozen shoulder. So, it is definitely not coincidental. She thinks that if Pfizer have not received a complaint like this, Pfizer need to document that.
