Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. I need to know more about the symptoms, like precipitating factors, factors that increases pain etcetera. Mostly, it s a gastritis and reflux disease. Do you have upper abdominal pain, nausea, bloating, burping, increase in pain on food, sour water feeling in throat or chest burning. If yes, then it will help further is assessing diagnosis. You should avoid fatty, oily and high calorie diet. Have some walk after having food instead of taking rest. Have multiple small meals instead of heavy meals. Have regular sleep habits and avoid stress. Lots of green leafy vegetables, fruits should be taken. Avoid smoking and alcohol if any. You can get prescribed tablet Pan DSR to be taken 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 and it s a musculoskeletal type of pain and needs prolonged NSAIDs therapy. Does this pain increases on deep breathing and coughing etcetera. If yes, it is a pain arising from lining of lungs and needs NSAIDs treatment and evaluation. Cardiac pain occurs usually on exertion and subsides with rest, may occur at rest if there is heart attack, goes to left arm and associated sweating, uneasiness etcetera. Anyway, get one ECG done to rule it out. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Sagar Makode
