My brother was wakeboarding this weekend at the lake and took 2 hard falls... one fall he smacked the back of his head and the other he hit his face. After both falls, he said he started coughing up blood and when he blew his nose, blood was coming out. He said he had a pounding headache later that night. Did he get a concussion? What do you think happened? He is 27 years old, 5 10 , in good physical health, works out 5 days a week, weighs about 175#.
