Suggest Remedy For Pain And Inflammation In Abdomen

I had a Esophageal Dilation done Monday and my stomach is burning and I feel like I have been on the edge of a cliff for three days. The anxiety is killing me -or It feels like anxiety. The doctor gave me Pantoprazole 40 mg to take 15 minutes before meals. I have a roller coaster feeling in my stomach - to much acid? is there something I can add to ease the pain and anxiety?
