<s>[INST] Hi, may I answer your health queries right now ?  Please type your query here... I am increasingly experiencing palpitations in my chest, regular occasional sharp pain in neck and aches in left chest. Family history dad triple heart bypass at53. Grandfather stroke at 47. I smoke. Since I was 17. I am 36 hrs. My doc keeps saying it stress. Is it? [/INST] Your question cannot be answered completely without more information. However, at 36, as long as you have no major risk like diabetes, smoking or cocaine use, the chance of heart as a source of symptoms is low. Your family history does count and low is not zero. I usually will review symptoms of reflux (burning, sometimes meal related, often lasting longer than 30 minutes or occurring at rest) and musculoskeletal pain (positional and localized with a finger) and recommend a trial of over the counter heartburn aid. If the symptoms fail to improve. You may find reassurance in a calcium scan. If your calcium score is very low, you can be reassured. If it is high, you and your doctor can use the information to decide how to address your risk and if any further testing is needed. </s>
