It feels like there is a bubble in my throat?

So i just got over Bronchitis and my throat is still a little soar and I am coughing a little. I woke up this morning and everytime i swallow it feels like a little bubble or something in the back of my throat. It doesn't hurt but its just annoying. I am a hypochondriac (well atleast everybody says I am) so I am freaking out. Any idea on what it is?
