headedness

    Laughed real hard, light headedness?

    Well I just watched this real hilarious video and was laughing pretty uncontrollably. I felt a bit of light headedness then felt almost like I was about to faint followed by what I guess would be best described as slight face twitching. Is this normal or are there any cardiovascular conditions...

    can someone help me with my constant light headedness?

    i know that's not the right word, but its all i could think of. i'm not hungry, and i never get up fast. i donated blood in this past november, i passed out and puked because i was underweight. someone told me that could cause long term effects? i need answers, migraines are also constant.
