Over 2 years out stomach pain

I went to the ER on Wed because I have been having belly button pain and burning on left and right sides and lower stomach. No throwing up, no constipation, and the CT scan was normal, blood work was normal, urine was normal. Can you believe the nurse in charge gave me NSAIDs for pain. I really worried. I've done well for two years and now this. I have an appointment with a gas doctor next tuesday I found on my list.  I'm taking fexiril for muscle spasams and that is and some gas X but nothing works.  I'm going to try and drink just peppermint tea for the next 24 hours and see what happens.  This pain is making me crazy.  Anyone seen this before?

Thanks Kathleen
