bloodwork, 24-hour holter,? and my cardiologist said everything looks good and normal, nothing causing concern.

However, I still have light chest pain (nothing intolerable) and I still have some palpatation through-out the day... anyone have any idea what might be going on? Specially since I had all the testing and everything's normal...! I dont understand if everythings normal what else could it be?
oh yea and I also had a heart ultrasound that also came out perfectly normal!
