Bob, curious if you have ever taken Imitrex? My symptoms started right after I took it for some migraines I was experiencing and was just wondering if it could be related? I agree I don't believe it has anything to do with acid reflux either. Have you ever had an Endoscopy done to see if that revealed anything? I have a referral to see the Gastro doctor but I'm not convinced it has anything to do with my stomach.
