Hi Your symptoms described with swallowing difficulty may be early PD.....but..... my husband had very similar complaint/symptoms........he saw a gastroenterologist who suggested that an endoscope be inserted down the esophogus....small lesions and scarring were visible at the top of the stomach/bottom of esophogus (caused by acid reflux). A balloon was inserted in the endoscope to stretch the esophogus scarred area.......and the problems disappeared (at least for now). He was told the procedure may need to be repeated again someday.....but for now he is ok. (He is now taking Prilosec for the Gastric Reflux. The procedure is an outpatient procedure......mild sedation.......total time approximate 2 hours from admission to release........he came home a bit "groggy" but after a nap was up and going at his regular pace. I am the PWP.......Don is "just the husband" as he describes himself. Good luck......Rita Weeks
