ELI5: When we are about to cry or holding back from crying, why does it make your throat hurt?

When you cry, you produce a great deal of saliva. During this, your throat's attempt to swallow that saliva presses on your glottis, which expands when you're trying to stop yourself from crying or making otherwise involuntary sounds. The glottis is the opening between your vocal folds. This act of pressing by your throat compacts your food pipe, which makes it feel "stuck".
