ELI5: What exactly happens when you lose your voice?
gpt
Your larynx is inflamed.  In there are folds of tissue that vibrate to make your voice when air passes over it.  When they get all swelled up, they can't vibrate like they could before.  Think about how difficult it would be to talk if your tongue swelled up, it's a bit like that.
