My 19 year old son was taken by ambulance to the nearest ER. (He s away at college) His symptoms: Started seeing dots and became dizzy. Dropped his phone out of his hand because he was really weak. Passed out and next thing he remembers is sweating in a chair. Campus security called paramedics. He s had chills all weekend and a migraine since Friday. Hit is his head during the fall. Has a bump on the right front. Hands are tingling. He doesn t feel normal, he says. I want him to see a specialist. I don t know how much assessment they will do. He s had a couple of concussions over the past 5 years. Tends to have migraines. I understand that until an assessment is done, we don t know for sure, what it could be. However, what are the possibilities? What should the initial assessment look like?
