This is a 68-year-old Caucasian woman without history of autoimmune conditions that presented to our emergency department with bilateral proximal upper and lower extremity muscle weakness, stiffness, and pain. She received the first dose of the Pfizer-BioNTech COVID-19 vaccine 2 days prior to symptom onset and 7 days prior to hospital presentation. Initially, she developed a mild headache and experienced soreness at the injection site that resolved the day after vaccination. Two days after receiving the vaccine, she developed acute onset of bilateral shoulder pain, morning stiffness that lasted at least 30 min, and weakness that started in her right shoulder and then progressed to her left shoulder. She also developed bilateral antero-lateral hip pain radiating into her thighs, stiffness and weakness. Over the course of a week, the muscle weakness and pain became so profound, that she was unable to ambulate.

That happened to mom as well.. 😞
