The symptoms of acid reflux can be very uncomfortable and painful and they are usually experienced when acid reflux or GERD occurs. Acid reflux is a condition that occurs when the tube responsible for transporting the food to the stomach from the throat is not able to handle the acid produced, stored, and used by the stomach in digesting the food we eat. This shouldn’t be the case because the walls surrounding the stomach should be strong enough to do its task without incurring any damage.
