over the last two weeks on three separate occasions i have felt as though my heart is being gently squeezed, a bit like a contraction, i can only describe the intensity as like a wave, starting very gently reaching a peak and then tapering off.  i am not in any pain but it is a very odd feeling
Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, you are mostly having simple muscular spasm but better to rule out any heart diseases first. So get done ECG, 2d echo and stress test (trade mill test). If all these are normal then no need to worry about heart diseases. Simple muscle spasm is more likely in your case. So avoid bad postures in sleep. You can apply warm water pad on affected areas to avoid such contractions. Don't worry, you will be alright. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
