Why does your throat hurt when you yawn?

A sore throat when yawning may be caused by several factors, including dryness in the throat, irritation from Allergies, or the stretching of throat muscles during a yawn. Yawning can also lead to the inhalation of air, which may aggravate any existing inflammation or infection. Additionally, if you're experiencing a cold or another illness, the act of yawning might exacerbate discomfort in an already sensitive throat.
