Gastritis?: If you have stomach pain frequently, you may benefit from an EGD exam by a gastroenterologist to see if there is any severe damage. Some people with GERD are infected with H.pylori and a 2 week treatment regimen can provide relief in some. Probiotics seem to help some people as well. Dietary changes may be needed. Limiting alcohol, soda, caffeine, spicy foods and citrus juices may help.
