My wife feels like a food pipe obstruction, which hurts her to some extent, especially after eating some dry solid food, like say, after swallowing chunks of overcooked white chicken. This feeling is related to lower portion of the pipe (from hest down). The feeling is like as though the food is not going down easily while the inside of the food pipe feels tender. No such feeling is present when eating softer food. Any suggestion as to what to do to eliminate this feeling. Thanks for any help!
