<s>[INST] I started getting sharp piercing pains in my left elbow about 4 hours ago and now they are happening at the same time as a sharp pain in my left chest area almost near the armpit...its consistant with muscle pain but I can't pinpoint the exact point of the pain...should i go to the ER? [/INST] Thanks for your question on Health Care Magic. I can understand your concern. By your history and description, possibility of musculoskeletal pain is more. But better to rule out heart diseases because left sided chest pain is common in cardiac diseases. So you should definitely consult ER (emergency room) and get done ecg and 2d echo. If both are normal then no need to worry for heart diseases. Your pain is mostly musculoskeletal in nature. So avoid heavyweight lifting and strenuous exercise. Avoid movements causing pain. Avoid bad postures in sleep. Start painkiller and muscle relaxant drugs. Apply warm water pad on affected areas. Don't worry, you will be alright. Hope I have solved your query. Wish you good health. Thanks. </s>
