I'm no doctor but it's possible you have a bit of acid coming back up your "pipe" and irritating your esophagus a little. That can make things feel "funny" when you swallow. I agree that stress can start all this or make it a ton worse. Try making sure you are drinking a lot of water.
The only negative thing about running to the doctor (for me anyway) is that they always want to do a bunch of tests, some of which are uncomfortable and all of which are expensive. I do have good health insurance, but I still don't like to spend the money unless I feel it's absolutely necessary. When doctors want to run tests on me, I get very anxious and imagine all sorts of things which make everything a lot worse. Usually I try to wait a little while to see how I do. Of course, if things get worse and home remedies don't help at all, then it's time to see the doc. But everyone is different and you have to do what you're comfortable with.
