These conditions included PMR-like symptoms following COVID-19 vaccine treated with NSAID (n = 1); symptoms emerging after diverticulitis and urinary tract infection resolving without treatment (n = 1); mild PMR symptoms along with elevated CRP, which resolved spontaneously without a history of infection or vaccine (n = 2); symptoms following COVID-19 infection treated with steroid injections and later with methotrexate and adalimumab (n = 1); and asymmetrical arthritis managed with prednisolone (n = 1). Here, CRP is linked to urinary tract infection.
