It is true that eosinophilic esophagitis and esophagitis from reflux have different treatments. The diagnosis is made via biopsy up and down the esophagus.
Swallowed Flovent is normally the initial treatment if eosinophilic esophagitis is suspected. It is not clear whether acid-suppression (i.e. Prevacid) can help in these cases.
There are small studies suggesting improvement in those who take Cromolyn, and this can be considered if the Flovent isn't working.
If the diagnosis for EE is negative (i.e. via biopsy), you can consider a 24-hr pH study to give a more definitive diagnosis for GERD.
These options can be discussed with your personal physician.
Followup with your personal physician is essential.
