i was at the moves last night and saw something funny and led out a quick hard laugh and then became so light headed i felt like fainting . well after that i felt weird so we left the movie. i rested a while and felt better , the next day i was out in the yard working on the car and all of a sudden got light headed again but not to the point of wanting to faint. since then i been feeling strange like im exausted but my body feels normal, i dont feel sick, and nothin hurts i just feel lil dizzy not much, im 22 and have no history of illness of this nature, some people say its just because my wife is pregnant. any ideas
