I had extreamly intense sharp pain last night. couldn't move and it hurt worse to breath. did i have a heart attack?

Heart attack: If you're still experiencing symptoms you should go to the er. Sharp pain is usually not the typical of a myocardial infarction. Also, it is not usual to have a heart attack at night and then go about your routine the next morning. Until a heart attack patient seeks assistance they usually continue to have symptoms.

Not likely: Sounds more like a lung issue or chest wall/muscle problem. If it persists or recurs, seek medical attention.
