Hello, Thanks for posting your query with us, From the description you have provided, it looks like you may have had a myocardial infarct (also termed as heart attack), but cannot be proven until and unless an ECG is taken during your next episode. I would suggest you to go to an emergency room for proper investigation and further management. If in that case, you would be provided with nitroglycerin sub-lingual tablets to take as an when you experience this pain. Meanwhile, I would suggest you to take some precautionary measures : - try to not involve in any tedious tasks - call for help during the next episode - if you have any associated diabetes or high cholesterol, kindly keep a check on it. Hope this helps. Thank you
