Grade: 4
After my race I lost 50% of my vision, tried to cool down my putting my head under cold water at a friends house but it didn't stop the symptoms. Gained back vision then got a migraine, went home quickly and slept for an hour, woke up and they us several times then back to sleep. Headache went down and it stayed for 2 more days
Lots of hydration and an easy couple of days. Headache is completely gone
