Lightheaded after Laughing...

Did you ever have a spell and you started shaking uncontrollable especially your head?

It just had this happen to my wife she had her pituitary tumor removed 4 years ago wondering if it has something to do with that

Hi, I'm a 13 year old boy and I have wrinkles around my mouth from laughing or smiling. I've had them for years. How can I get rid of them and don't say "stop laughing" because I always laugh.
