(KETV7) – Just weeks ago, Creighton Prep sophomore Sean McMahon was working out with a friend when a sudden headache changed everything.
“Me and my friend, Liam, we were working out at the JCC, and just mid-set, I started to get this really, really bad headache,” McMahon said. “I didn’t really know what was happening.”
Moments later, he became sick and disoriented. Someone in the locker room called 911, and McMahon was rushed to the hospital. Doctors later discovered he had an arteriovenous malformation, or AVM, an abnormal tangle of blood vessels in the brain that can rupture and cause bleeding. CONTINUE
