Gerd/ constipation

Has anyone experienced burning of the stomach with occasional burning feeling in throat, i feel bloated , constipated, and have constant belching after eating and gets worse at night.

I was diagnosed with SIBO last year, i did two rounds of antibiotics. Im on pantoprazole, have been taking probiotic. I ended up taking Gaviscon because the burning sensation was so bad.

I ended up taking Magnesium citrate pill last night which did work but my symptoms remained the same.
