It's really hard to speculate as to whether or not you should be concerned, so kitt is absolute right that you should go visit a physician to have them evaluate you. It would be good to see a physician soon to rule out the possibility, although probably very rare at your age (especially without accompanying pain or other genetic disorders such as marfan syndrom or ehler danlos), of aortic aneurysm.
