My son was very active with a friend today spinning on a around about. Ten minutes later he looked pale and eyes rolled back i turned and caught him before he fainted. He reported his ears felt weird and he felt weak in his legs and dizzy. We drove home , on the drive home he said he had stomach ache but felt better. and 30 minutes later after getting out the car it happened again and i caught him. once in the house it happened again this time he hit the floor though i didn t see just heard and he lay there fir a few minutes there did not seem yo be a loss of consciousness . What could be the problem, i have had the flu and he has a running nose but is well otherwise. Please help worried.
