Hey my names ashley im 20 years old. when i was 19 i was diagnosed with mitral valve prolapse/regurgitation at a normal doctors visit. he said it wasnt a bad case i just had to take it easy. my yearly checkup is in august of this year, but i need to know if i need to make an earlier appointment. Sunday when i got home i had a "spell" as my mom called it. I became dizzy and lightheaded fast. my mom thinking it was the sun told me to go inside. when i started doing my daily chores it got worse. everytime i stood up i became dizzy, it was hard to breathe and when i walked i felt like my legs were shaking. i decided to just sit down and relax and drink water and after about an hour it went away as fast as it came. its never happened before so any help on what it was and how to prevet it would be greatly appreciated.
