<s>[INST] today I have had pain that comes and goes and is short and dull and it is in my heart. I have no shortness of breath or other symptoms. I have had a sore throat and lung pain all on one side as well. My doctor gave me nasal spray but no xrays i've been on for one week for the same symptoms. [/INST] Thanks for your question on Healthcare Magic.I can understand your concern. Possibility of musculoskeletal pain is more likely in your case. But better to get done ecg too rule out heart diseases because you are having left sided chest pain. If ecg is normal then no need to worry for heart diseases. Apply warm water pad on affected areas of chest. Take simple painkiller like paracetamol or ibuprofen. Avoid movements causing pain. 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. </s>
