uncontrolled GERD with burning sensation on tongue/mouth
I have acid reflux for about 8 years, which has been mostly under control with Nexium 20mg/day. But, after carrying very heavy boxes about 6 months ago I had a flareup and since then the reflux is not under control, and includes waking every few hours at night with reflux feelings, which is generally sensed as a burning sensation in my mouth. Increasing Nexium to twice a day didn't seem to help, (I take Tums or Gaviscon for symptoms and haven't had coffee in years).
Had an endoscopy which showed only that I "may have a hiatal hernia" (although I thought he'd see a large one and an open LES). But – after the endoscopy I felt better. But the doctor said the procedure only diagnoses and does not cure and didn't believe me.
I went down to again taking 20 mg Nexium once a day. 24hr Ph test showed only 5 acid/partially acid incidents (done on a day I felt reasonable) and showed I don't have non-acid reflux.
Meanwhile, a few weeks later I again feel constant symptoms, such that all day and night I feel a burning tongue. (two weeks ago I had a large calcium pill which caused me heartburn and I wonder if might have contributed to the flareup recurrence)
Any suggestions as to how to get the GERD back under control as it was before the flareups?
