What could cause mild chest pain without heart attack symptoms, and a normal pulse rate?

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern. I need to know more about the symptoms, like precipitating factors, and factors that increase pain. It can be a gastritis and reflux disease. Do you have upper abdominal pain, nausea, bloating, burping, increase in pain on food, sour water feeling in the throat, or chest burning? If yes, it further supports the diagnosis. You should avoid fatty, oily, and high-calorie diets. Have some walks after having food instead of taking a rest. Have multiple small meals instead of heavy meals. Maintain regular sleep habits and avoid stress. Eat lots of green leafy vegetables and fruits. Avoid smoking and alcohol if any. You can take the tablet Pan DSR (Domperidone and Pantoprazole) 40 mg before breakfast once a day for 2 weeks. Secondly, does this pain increases on applying pressure over the area? If yes, it could be costochondritis which is a musculoskeletal type of pain and needs prolonged NSAID (non-steroidal anti-inflammatory drug) therapy and Diclofenac gel application. Does this pain increase in deep breathing and coughing? If yes, it is a pain arising from the lining of the lungs and needs NSAID treatment, and if persistent then it needs evaluation. Also, please let me know if you had any trauma during excessive exercises, or lifting heavy weights. It is not a typical site for heart pain, and age is also not compatible. The chances of heart disease are less, still, one ECG (electrocardiogram) if available can be done. I hope this helps. Thanks and take care.
