Therapeutic measures were taken as a result of polymyalgia rheumatica.  Clinical information: The patient mentioned that about 10 days after receiving the BioNTech-Pfizer COVID-19 booster vaccine (BNT162b2), she started developing extreme fatigue, widespread pain throughout her body, and generalized weakness. She mentioned severe pain and stiffness in the shoulder and hip girdle to the point that she was unable to get up from the bed and had to use a cane for ambulation. She also endorsed a band-like headache around her temples as well as blurry vision. No jaw claudication symptoms were reported. Initially, she had flu-like symptoms after the COVID-19 booster that gradually resolved, but the body aches and fatigue continued. Her musculoskeletal examination showed decreased range of motion in the shoulder and hip joints but was unremarkable for any joint effusion, synovitis, or tenderness. Muscle strength was 5/5 in the upper and lower extremities. No temporal tenderness or bulging was noted. Initial laboratory studies showed normal complete blood count, basic metabolic profile, and thyroid function tests. Her Inflammatory markers were extremely elevated; ESR was 108 millimeters/hour and CRP was 150 milligram/liter. With high clinical suspicion of PMR and giant cell arteritis (GCA), the patient was started on prednisone 60 mg daily, and a temporal artery biopsy was scheduled. She had left and right temporal artery biopsies, which were negative for any histopathological abnormalities indicating no GCA. She was instructed to taper her prednisone dose gradually. At her two-week follow-up appointment, the patient showed a significant response to prednisone treatment, with improvement in her shoulder and hip girdle pain and stiffness. Her ESR improved to 54 and her CRP improved to 29. Her headache and blurry vision persisted despite a negative temporal artery biopsy, and she was referred to an ophthalmologist for further evaluation of blurry vision.   Conclusions: The temporal relationship between COVID-19 vaccination and PMR has yet to be established, but our case report will add to the literature review. We hypothesize that the COVID-19 vaccine triggered the auto inflammatory state in our patient leading to PMR. Myalgias are a commonly reported adverse effect of the COVID-19 vaccine. We emphasize that physicians should pay attention to persistent myalgias and obtain ESR and CRP levels when appropriate to evaluate possible PMR, which response well to corticosteroid treatment. However, these cases are rare and should not prevent the population from receiving the vaccine, as the benefits of the COVID-19 vaccine outweigh the risks.  The information on the batch/lot number for BNT162b2, BNT162b2 omi ba.4-5 has been requested and will be submitted if and when received.
