 10 y/o RHM awoke with a bilateral parieto-occipital HA associated with single episode of nausea and vomiting, 2 weeks prior to presentation. The nausea and vomiting resolved and did not recur. However, he continued to experience similar HA 3-4 times per week during the early morning upon awakening. He never felt the HA awakened him from sleep. The HA were partially relieved by Tylenol or Advil, and he distracted himself from the pain by remaining active. One week prior to presentation, he started to experience short episodes of blurred vision and diplopia. He also became fatigued, less active, and frequently yawned.
