Hi sir, i am having shortness of breath and tightness of chest area with mild chest pain. most of the time it happens at night when i was alone.

Chest Pain: Chest pain from a narrowed heart artery, called angina, typically occurs when you are active or exercising and goes away when you rest. It is often a tightness or pressure or burning in the chest or neck or arm. If you are only feeling symptoms when at rest at night and not during exertion, it probably not your heart, but i suggest you see your doctor.
