Thanks for your question on Healthcare Magic.
I can understand your concern.
Possibility of muscular spasm is more likely.
But better to rule out cardiac
chest pain as you have many risk factors for heart diseases like obesity,
hypertension, stress, age of 50 years etc.
So get done ecg, 2d echo and
stress test.
If all these are normal then no need to worry for major heart diseases.
Avoid stress and tension, be relax and calm.
Try to loose weight.
Don't worry, you will be alright but first rule out heart diseases.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
