Well, obviously you know it can. As to why? You should be asking a doc, not us, LOL!

If you're still feeling like you're choking and having difficulty swallowing or breathing, yes, you should go to an ER or at least an urgent care clinic - there are plenty of those around nowadays where you don't have to have an appointment. Tell them you're having difficulty breathing, and you should be seen right away.

Hope you find out the problem and resolve it soon. Meanwhile, if gargling with salt water helped, soups, teas and other hot liquids probably will, too.
