Symptom narrative

Patient received the vaccine on Sunday, 10/26/25, and immediately began to complain of a headache and a low-grade fever. Over the course of the next couple days, patient continued to complain about his head hurting. We treated the headache with Advil and Tylenol. Over the weekend he continued to complain about the headache, and I said to him that I would take him to the doctor Monday morning if he still didn?t feel well. In the middle of the night on Sunday, early Monday morning (11/3@3am), patient came in crying that he had a terrible headache. This persisted so long that his father took him to the emergency department. They they tested him with a CT scan and three lumbar punctures (2 were unable to draw enough CSF) to determine if he had meningitis. Patient did not have meningitis, and was released. His headache persisted such that on Thursday. November 6, patient was admitted to the emergency department and ultimately to the hospital for 2 nights. He had an MRI and another lumbar puncture. Today is November 21, and patient continues to have headaches in which the pain ranges from a 3-8 out of 10. We are currently under the care of a pediatric neurologist.
