Hello dear I understand your concern Acid reflux cause pain in the chest and back. So I think it is due to GERD. I would suggests to consult the gastroenterologist and undergo urea breath test, barium meal Xray and esophageal Ph monitoring to confirm the acid reflux. Doctor will give following advises: Tablet esmoprazole 30 minutes before meal Syrup mucaine, take adequate dietary fiber and supplements like senna Tablet metoclopramide at the bed time Take small frequent meal rather than large meal Take diet like rice, banana, applesauce, yogurt, buttermilk and curd Avoid smoking and alcohol, beverages Do not go to bed just after food. Avoid stress and do regular exercise like walking and yoga Hope this may help you Contact HCM for further health query Best regards Dr. Sagar
