I have been diagnosed with h pylori. I m on triple therapy. It s my third day of taking this therapy. Problem started with a stitch like pain in my left side waist. Had some painful gas over the next week and took GasX. One week ago I had such bad and painful trapped gas in my stomach that I thought I was having a heart attack! Could not stand up straight and felt nauseous. After one hour the GasX worked and I did numerous huge burps which got rid of it. Nice! Gas kept coming back though at random times daily for the next few days until I went to the doctor. I also have a gallstone and am worried that my symptoms maybe related to that rather than the h pylori. How long does triple therapy take to start symptom relief? Should I carry on taking all these meds or have testing to determine the root cause of my symptoms? I m taking 1000mg amoxicillin, 20mg omeprezole and 500g clarithromycin twice daily. I have diarrhea (started today), original pain in left side waist still, and intermittent gas/bloating. I woke up with gas/indegestion this morning. Thanks.
