Thanks for your question on Healthcare Magic. I can understand your concern. Possibility of musculoskeletal pain is more likely. But since you had heart palpitations, better to rule out cardiac cause for your chest pain. So get done ecg, 2d echo and stress test (trade mill test). If all these are normal then no need to worry for heart diseases. Apply warm water pad on affected areas. Take simple painkiller like paracetamol or ibuprofen. Avoid heavyweight lifting and strenuous exercise. Don t worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
