I had terrible acid reflux after my gastric sleeve on December 12th. Every time I'd swallow, I'd have to burp and then a radiating pain would occur across my back. My doc said it was very bad reflux and prescribed me Calafate 4x a day, in addition to the esomeperazol that I was already taking. The pain went away after 5 days...thank God! Talk to your doc about taking something for it because there is relief out there.
