Hello all! I'm hoping to get some insight on what's going on with me. About 2 weeks ago I started feeling unwell. Pain in my stomach, pain in my back. I currently take protonix for gastritis that was diagnosed a couple of years ago. It got to the point where the dr. put me in the hospital for pain control. I saw the surgeon and he stated that I have a hernia and also have the gastritis. They changed my medications around to protonix, questren, and carafate. I was released from the hospital on Friday. Since then I've been vomiting daily after taking the questren, and still having the pain in the stomach and the back. I have a doctor appointment today and then on Wednesday to see the general surgeon, but has anyone heard of having more issues since diagnosis. I've also noticed that my stool is black too, which was very strange. I'm tired of feeling the need to vomit all the time, it isn't a good feeling at all.
