Hi and thanks for the query,
The most probable cause in my opinion should be gastroesophagal reflux disease. A history of oral flush, epigastric pain
or specific pain syndromes with particular foods could be suggestive. a clinical evaluation accompanied with a fibroscopy, PH measurement and Manometry of the lower esophagal sphincter to make an exact diagnosis. The opinion of your gastroenterologist could be useful. avoid spicy foods, pepper and caffeine containing substances for now could help.
Thanks and kind regards. Bain LE, MD.
