My mother is taking Ganaton 50 and Omez 20 as she suffers frequently heartburn in between the breast and pain just on the backside of the neck after having evening snacks. We consulted gastroenterologist and he prescribed medicines Ganaton50 , 3 times a day and Omez 20, once a day before meal. It's been 2 days after taking medicine but the problem persists post evening snacks. Sometimes we have chowmein from restaurant as snack and sometimes just brown bread and peanut butter. Kindly help.
