My dangly bit in my throat us swollen and it hurts to swallow what does thus mean

Uvula: That dangly thing is called a uvula. When inflamed it suggests that you have some type of upper respiratory tract infection. That may produce the symptoms you are having. If this does not get better with saline gargles or you have any difficulty breathing, would see a doctor asap. Get better soon.

A few things: May have strep throat. See your doctor for testing and treatment. You may also have tonsillitis.
