Most allergy testing is, I believe, IgE-based and will show you if something will produce an immediate reaction (minutes to hours). Food allergy uses IgG and IgA reactions and are designed to show reactions that will show up in a couple of days to several weeks. With food intolerance, the reactions might only show up days later, so it makes it difficult to pin down.
You might want to consider checking with a functional medicine doctor who has experience in food intolerance issues - not all do so check them out thoroughly.
Food intolerance can produce a number of symptoms similar to those you've mentioned - including the migraines. Migraines are very common in those with IgA-based issues with gluten.
It seemed to help the first couple of weeks but then things went back to normal. I have had an allergy test done before and found out I am not allergic to anything. Would the food intolerance test be something different? I have also found out that while I can't tolerate water I am able to drink sparkling water.
What happened when you went on the exclusion diet? Did it help? Considering you said you can't handle ice cream or milk, did you ever exclude all forms of dairy from your diet?
Have you considered food intolerance testing?
I went to an ENT and he placed a tube down my throat but all was normal. I have noticed that almost every time I have a regurgitation episode I almost always get a migrain headache over my right eye and have to have a bowel movement. I take Prilosec once a day and Reglan about every 4 days. Any more suggestions on what I should do next?
Well, without a clinical evaluation it would be difficult to comment specifically on the situation. While the GERD is best managed by a gastroenterologist and migraines by a neurologist, depending on the severity of the condition and the medication side effect profile; the ‘lump sensation’ in your throat is called globus in medical terms. The feeling of a lump indicates that one of the muscles along the way is tightened. Although globus usually doesn't represent a serious problem, when present steadily for more than two weeks or intermittently for two or three months, a thorough examination of the oral cavity and throat is in order, especially in smokers. The most common cause for this symptom is infection, usually viral. Masses and tumors and incoordinated contraction in the upper oesophagus and psychological stress could also cause the sensation. It would be best to have this evaluated by an ENT specialist for an accurate diagnosis and appropriate management.
Hope this helps.
