My son was standing and talking to someone outside. When he went to walk away his vision went black, he had trouble controlling his extremities and felt nauseated. When he got back inside he sat down and said he was sweating. After a few minutes he said he still feels sick and has a headache but his vision is better. What could have caused this and is there anything we can do besides wait? Thank you, Mike Howard
