@dea:

There are a lot of informative posts here for you to read and learn about all the testing that is out there.

But in my experience, a doctor will hesitate to use them unless
there are symptoms that are persistent and serious.

Most doctors wait and see how much you complain, and it would
help for you to keep track of all the swallowing problems daily.
Say 3 times on Sunday--log the times and type of food
or 4 times on Monday--log the times and type of food.
etc. When you present a listing of persistent uncomfortable
incidents, THEN you may get further evaluation. If you were in a nursing facility or hospital, a nurse would be logging these times. Since you are at home, you need to keep a record yourself so your doctor can see and evaluate whether you are having troubles needing interventions.
