I have been experencing passing out spells when they happen my cheeks get flushed and my heart rate goes up and i can hear it beating in my ear?

Need evaluation: You may be describing psvt (paroxysmal supraventricular tachycardia). Some people are also born with accessory bypass tracts. The heart rate in the former could be 220, in the latter >300. You need evaluation to rule out such a serious cause.

Passing out spells: If you have not sought medical attention for this, then you need to do so as soon as possible. Even at your young age your symptoms could represent a life-threatening cardiac or neurologic condition.
