My 16 yr old son plays football and basketball, he went away this weekend with his mother and they drove to Disneyland from Stockton Ca, he woke up this morning feeling lightheaded and blood in his mouth, he didn t go to summer school but he did go to football practice, he says he s been feeling horrible all day and just wants to rest, he wants to wait a few days to see if he feels better, should I wait to see how he feels in the morning? Or take him to emergency right now?
