Thanks for your question on Healthcare Magic. I can understand your concern. Possibility of musculoskeletal pain is more likely. But better to get done ecg to rule out heart diseases because it is left sided chest pain. If ecg is normal then no need to worry for heart diseases. Avoid movements causing pain. Avoid heavyweight lifting and strenuous exercise. Avoid sudden jerky movements of chest. Apply warm water pad on affected areas. Take simple painkiller like paracetamol. 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.
