I am not an expert but it sounds like you had some acidic irritation to the esophagus from all of the vomiting. All that bile may have caused inflamation. You should see a GI and have him determine what you should do to get relief. He might start you out with something to heal the irritation. Maybe even suggest an EDG scope to see what else might be going on. All that vomiting could have caused other issues that you didn't have before. you'llbe fine. Just get checked. I had a scope done a couple weeks ago. It was very easy because they put you out usually. Hope you get well soon.
ps I never had heartburn and reflux problems either, but now I know that I do have GERD. Your symptoms do sound similar.
