It sounds like what happened to me when before I was diagnosed with Asthma. Asthma can develop, so it would probably be best to go to the doctor and have some tests done.
Hey Steph0112,
I would definitely see a doctor. Friends of mine have had this problem and sometimes it turns out to be just jolts of excitement, like a quick lapse of adrenaline being pumped into your heart which isn't anything to worry about, and other times, it could be something serious like a Heart Murmur. I am not saying "omg time to panic" but in your leisure, I would definitely see a doctor.
