I get the chest pains with my GERD and lying down makes it worse. I have to sit up and wait out the attack, which can last from a half hour to several hours. I am also throwing up stomach acid. How often have you had these attacks? Did you try to take any antacids and if so did they help at all. Many people experience heartburn without it being a more serious condition. Alot depends on how often you get the attacks. What type of food brings on the attacks. If you are having these frequenltly you might want to get checked. Medication helps many people, I unfortunately am not one of them.
