hi there, your complain is alittle vague but if the burning sensation is in the epigastric region then it could be due to
gastric reflux or
gastritis. You could try some
antacid and a change in your food habit for a few days like taking small meals low in fat and spice at regular intervals and see if it helps. If you are tensed about something or lead a stressful life you need to relax and take up some activity like meditaion or
yoga to calm you down. Take care.
