[ELI5] When you eat ginger, wasabi, mustard etc. you get a feeling on your tongue and in your nose. What is that feeling and what is it coming from?

Wasabi and mustard contain a special compound, called AITC. This compound causes your eyes to water, because it interacts with the nerves in your nose and mouth. Ginger contains gingerol, which works similarly. Both of these compounds are similar to capsaicin, which is contained in hot peppers.
Forgot about the second part of the question: The feeling is your nerves being made more sensitive to heat, which in turn makes your body react.
