Go and see a qualified medical practitioner (a Doctor).
If you have a heavy chest feeling that is not tight and you are having no breathing issues, it should still be checked out. It could be something as simple as acid reflux but it could be more severe.
Chest flutters are also know as PVCs or Premature Ventricular Contractions. The can be caused from anxiety, fatigue, too much exercise.
It could be stress, but see a Physician to be sure.
Pain is your body's way of telling you that something is wrong. I suggest that you go to hospital or see a doctor as soon as possible.
Very Carefully !!
In these days in school feeln tight is just like feeling burnt but a "cooler version"
A tight chest gets better by calming down controlling your breathing and drink water.
I have chest feels tight a lot and it goes down in tightness throughout the week then on Sundays it is always the worst I don't know how to fix it but if it's at night I just prop myself up with a small pillow
It's a 'tight' chest and is something that asthma sufferers get.
