On ranatadine & gaviscon for gastritis. im getting no relief my chest aches/burns all day, even wakes me up. can't take omeprazol. what's a good pain relief option? i've changed my diet, risen my bed, i don't drink or smoke. or eat 3hrs before bed.

I have a few: thoughts, but you will need to continue to work closely with your gastroenterologist. Sometimes a different (from omeprazol) PPI may be effective, i.e pantoprazole or esomeprazole. Maximal doses of the H2 blocker (ranitidine) and PPI if tolerated (twice daily). Try sulcrafate. Baclofen can reduce the rate of sphincter relaxation; pain modulator such as trazodone; surgery as last resort.

Need review by GP: Your next step is to talk with GP and decide whether you need a test for H Pylori and/ or refer for a gastroscope
