Chest gets tight im guessing anxiety.heart checked ok as well ss lungs. no clots found. whats best ways to convince myself it anxiety n or treat it?

Anxiety is a fear : Anxiety in not always rational and there is no simple test for it, usually it is caused by a brain chemistry imbalance, thought to be low serotonin. There are medications that raise serotonin levels and cause anxiety to subside. If chest tightness, shortness of breath and other potentially dangerous symptoms are present a medical work up should be preformed to rule out a serious problem first.
