Hi....i am a 50 years old lady.........i have gone through all websites discussing various types of chest pains and their possible causes.....but never found any match with the type of chest pain i am used to have since last 25 years or so.... I have a continuous painful ache with heaviness and tightness only at left side of my chest ..probably at or near heart muscles which i) is triggered just after a) heavy periods, b) after crying or weeping for long c) shouting with strong emotion and d) lack of sleep for 2 to 3 nights ii) remains for 2 to 3 days but gradually subsides with good rest iii) temporary comfort and relief is felt with massage or application of volini / muscle relaxant at the site of pain or even upper back on left side just posterior to heart muscle
