Symptom narrative

Patient had an episode of syncope that lead to an injury that caused concussion symptoms following his first dose of Flumist. He was seen/treated in the ER on 10/22/2025 and diagnosed with syncope and collapse, and loss of consciousness (30 mins or less). He had labs, a chest Xray, and a head CT. He followed up with our office post-ER visit where he had additional labwork completed. Rapid flu test was negative. Provider is concerned that patient's syncopal episode occured as a direct reaction to the dose of FluMist. Patient's main findings in office on 10/24/2025 are a blunt affect and eye muscle pain with upward gaze. The provider is keeping him out of school x 1 week for recovery/brain rest and having him abstain from sports/physical activity for 2 weeks after headaches resolve. Plan to re-evaluate him in office again in 2 weeks.
