The events "vertigo", "pain in the eyes", "blurred vision", "intense headache", "hypersensitivity behind the eyes", "when the the patient opens their eyes they have difficulty", "nausea", "vomiting" and "sea sickness" were evaluated at the physician office visit and emergency room visit. The patient underwent the following laboratory tests and procedures: computerised tomogram: (16Mar2022) negative; magnetic resonance imaging head: (16Mar2022) negative. The patient had taken the booster dose of the Pfizer Covid vaccine 2 months ago and now experiencing vertigo. The patient also had hypersensitivity behind the eyes, when the patient opens their eyes, they have difficulty. Patient had onset of vertigo, nausea, vomiting- similar to a severe sea sickness, blurred vision, pain in eyes, and intense headache. Patient went to emergency room and underwent MRI and CAT scans, which were negative. Patient states this episode feels like a super intense version of the side effects he experienced post-booster vaccine, including lethargy. Patient had very mild symptoms about 8 weeks ago right after the booster, now more intense. For the event nausea, the patient now has mild symptoms. Vomiting was resolved. Pain in eyes was less severe. Blurred vision and intense headache affected the patient's activities of daily living and work. The patient saw an ear, nose, and throat doctor on 17Mar2022, for a possible inner ear issue, and as of yet, he was negative. The patient will follow up with a neurologist. Physician would like to rule out thrombotic attack in brain or optic nerve associated with 60 days post vaccination. Reporter seriousness for vertigo, pain in the eyes, blurred vision, intense headache was medically significant. Reporter seriousness for nausea, vomiting was not serious.
