Pain in my left hip?

Whenever I'm walking, my left hip gives me sharp shooting pain. It's not so severe that I burst into tear, can't walk, or abstain from activities, but I don't feel it when I'm sitting down. I tried Googling it but I'm not sure whether half the results apply to my age group (I'm almost 15). Should I tell my parents. even though it's not affecting me physically? Will the pain worsen? Thanks for any help :)
