I have had a lot of problems with reflux myself; it started before I was banded. An endoscopy confirmed the diagnosis of hiatal hernia. I had 1/2 my stomach protruding upward into my chest due to the hole in my diaphragm. It was immediate relief. However,now I am 21mo postop from hernia surgery and am again suffering with severe reflux. I had a fill 5mos ago that was tight but I dont think too tight as I can eat 1cup food. My surgeon thinks the hernia has returned so I go for an endoscopy next week. I think you should have one if you are sure your band isn't too tight. Have you tried Nexium prescription for reflux? The pain in your ribcage area sounds like reflux. Do you have fluid backing up into your mouth/nose during sleep? If you have a recliner, try sleeping upright a few nights. If this helps it must be reflux - which could be treatable with meds or may require surgery like mine did. Good Luck!
