Thanks for your question on Chat Doctor. I can understand your concern. Left sided chest pain should always be evaluated first for heart diseases. So better to first get done ECG and 2d echo. If both are normal then no need to worry about cardiac diseases. Sometimes musculoskeletal pain can also cause similar symptoms. So avoid heavyweight lifting and strenuous exercise. Avoid movements causing pain. Avoid bad postures in sleep. Take painkiller and muscle relaxant Chat Doctor.  Apply warm water pad on affected site. Don't worry, you will be alright. But first rule out heart related diseases. Hope I have solved your query. Wish you good health. Thanks.
