Stomach burning

Has anyone experienced stomach burning before? I have had bad burning for thr past few days. It’s really bad after eating and wakes me up at night. I have been dealing with occasional burning for a few months. My doctor tested me for H. Pylori, which was negative and has me on rabeprazole 40mg a day, which is not helping at all.

I have never had burning daily like this before and am worried. I called my doctor’s office and they cannot take me until January 16th, so I’m planning to go to a clinic tonight. Just wondering if anyone else experienced this and what helped you?
