<s>[INST] Hi, last night I experienced something unusual that I cannot really explain it. I felt like my heart was gonna stop. Today my upper back hurts right in the middle. I cant really tell if its my spine that hurts too. My left hand hurts, kind of tingling too. Minor chest pain also appeared. Am I at risk of getting a stroke or heart attack? [/INST] Hi, Your symptoms looks very atypical. Chances of getting a heart attack depends on multiple things like age, sex (male are at more risk), associated risk factors like diabetes, hypertension, smoking, abnormal lipid profile. So you need to do certain tests to rule out the cardiac events like ECG and 2D Echo. Also check your BP and blood sugars routinely for risk assessment. Hope I have answered your query. Let me know if I can assist you further. Thanks, Chat Doctor.  </s>
