Also had the regular flu shot for older people on that Friday, but did not have side effects except swelling in the arm. Is not thinking very clearly right now Very odd side effects: Initially was fine had soreness in the arm. The patient had the shot at 7AM on 10Oct2022. As the day went on, started to feel like it got tighter in her body. Started to notice that she was having almost like involuntary muscle spasms. By later that evening, after 7PM, her jaw started to turn to the side as it was going. Her jaw was straining and pushing to one side, her teeth were clicking. Her tongue went down. Her jaw went one way and her face went another. Then had tightness in thoracic area, it just spasmed. When she tried to move her arm became really sore. Taken Tylenol, but that did not seem to relieve it. Did not sleep at all couldn't get comfortable, couldn't get comfortable. She was very cold, icy cold. Happened all within the 24 hour period. She would say she had the normal aching and then feeling fatigued, but that all was regular and doesn't matter. It was by dinner time, 7PM at night, things got worse. She was out of work yesterday. Was really miserable, it is more Flu-like. Still had tightness in her jaw, but jaw wasn't going one way and face another. Had tightness in her chest. Facial spasms have subsided. The overall fatigue seems to be the same. Arm was still sore but not all the way down to the wrist. Soreness is just from the elbow and up, it is normal soreness. Still having the coldness, but that's fine. Just feels very off. She had this severe reaction with a drug happen before, but it was a long time ago. Product name is unknown, it was probably 50 years ago. Treatment included taking Tylenol Extra strength caplets; 500mg per caplet, Dose: two caplets every 6-7 hours by mouth. Probably should have called her doctor when she was having the convulsions. Was not thinking very clearly. Tylenol didn't relieve her symptoms including soreness of the injection arm. Recognized the symptoms of her jaw turning and was very nervous of that. She was diligent, had her son check on her quite often. Could not tell if maybe getting the Flu shot on Friday might have been too soon. But she just had soreness in the arm from the Flu shot Its the one they give for seniors She has gotten all of the other COVID-19 Vaccines. Told Dupixent would not interfere with Bivalent COVID-19 Vaccine. The reporter wanted to know are there any other medical conditions that we should know about. Does not think anything was relevant. She does not generally take aspirin. Family Medical History Relevant to adverse event included None. Felt more like a reaction to her. Felt like the drug reaction she had, maybe twenty years ago. Remembered that off feeling and the symptoms with her jaw and teeth cracking on each other. Previously the drug reaction happened probably 50 years ago. It did feel like muscular spasms, not shortness of breath. She has had every one of the COVID-19 vaccine shots, this is the first one that she had a bit of problems with.
