[ELI5] What's happening when you take a pill, but it feels like it's caught in the back of your throat?

A few possibilities. 

1. The pill actually is lodged. Fairly uncommon but some people have difficulties swallowing pills.

2. The pill rubbed/scratched against the back of your throat and you're feeling that, not the pill.

3. Psychosomatic. There's no pill but the thought/idea/fear of the pill getting lodged is causing the sensation.
