Hi. I believe it could be associated with a gastric issue (e.g. hiatus hernia, gastroesophageal reflux disease, peptic ulcer diseas, etc.) requiring a change in lifestyle, avoid NSAIDs, avoid smoking, avoid alcohol, avoid stress, avoid fatty/fried/oily/spicy food, avoid carbinated drinks, avoid long gaps between meals, have 5-6 smaller meals in a day instead of 2-3 larger ones, avoid stress, drink plenty of water, and avoid overeating. Along with this you can initiate an antacid like lansoprazole 30 mg one tablet every morning for as long as you need. You also need to understand that I am working with limited information, and in case these suggestions do not help then write back to me in detail. Best wishes.
