I have had that exact symptom for a couple of years now. I had two upper GI barium swallow tests. The first time, they found a small hiatal hernia. The 2nd test found nothing. Maybe the hiatal hernia is the sliding type. Can a hiatal hernia cause pain like that?? I am at a lost. The pain is always there, sometimes worst than other times. It feels like a gnawing discomfort and it's on both sides. Sometimes it feels like it's straight across the top of my stomach, directly under my ribs. Sometimes it feels like a gnawing hungrey pain, but there were no ulcers found on my tests. It is very annoying, and I'm not sure which route to go. It doesn't match gallbladder disease. I also had the GB ultrasound but found nothing.
If you can find a possible answer or relief, please post back again and share it with us.
thanks for posting !
