I have occasional chest pains. the pain is sharp. i'm having mild mvp with mild regurgitation. anything to be worried?

No: It may not be cardiac at all. Try some antacid/H2 Blocker/Proton pump inhibitor.....see what happens. Also minimise spicy hot food, maintain regular food habit( Time). Anxiety may be one of the issues.

Chest pain: Usually no problem in 21year olds but as you have some cardiac findings, its a question better asked of the Doctor who is most familiar with you, your history and examinations.
