Your description about the pill and crunchy things like nuts feeling like they get stuck sound like something I had many, many years ago.
It was a pouch which is a pocket in the throat. It may cause difficulty in swallowing, sensation of a lump in the throat and troublesome regurgitation of food. Food may become lodged in the pouch.
Seem to remember the first ENT did not see it but some time later another did. Over time it fixed itself.
