Hello, I've had "silent GERD" and costochondritis for a few years. Lately I feel a twinge in my chest and they're only relieved by burping. This can go on for hours. It doesn't feel like it comes from my stomach or esophagus, but rather from my chest cavity. My doctor says my gallbladder and liver are fine. I'm trying to quit my PPI because of bad side effects, but I don't know if that's having an effect. I'm only 54, so I am too young to feel this old. Can anybody help?
