Had dysphagia. 2 endoscopies showed esophagus as normal. zero gerd symptoms at all. nexium (esomeprazole) cured the dysphagia. what do i have? can a gi answer-thanks

Consider these...: Difficulty swallowing ("dysphagia") can be distinguished as a "transfer" problem (difficulty moving food from mouth to top of esophagus), "transit" problem (difficulty moving food down the esophagus), "spasm", gerd (due to sphincter problems), or obstructive (webs, rings, strictures, ulcer, tumor). MIght still want to see a gastroenterologist (gi doctor) for evaluation & further treatment options.
