Acid reflux/Gerd

Advice on dealing with Acid Reflux. Have been diagnosed with gallstone and hiatus hernia.

Had a foot problem recently, took Naproxen for a few weeks and it has mucked my stomach up, prescribed Esomeprazole.

Just want a bit more advice, as upper abdomen and lower abdomen is burning

I also take Rantidine as well.

I have a consultation in May regarding Hiatus Hernia and operation in June to remove Gallbladder.
