The outer ear becomes painful upon touch. Typically, during acute inflammation of the external auditory canal, symptoms such as swelling and discharge are present, and touching the auricle causes明显 pain. Additionally, if a boil develops in the external ear canal, obvious ear pain or pus discharge after rupture may occur when the helix is touched. Another possibility is perichondritis of the auricular cartilage, which can also cause significant pain, local redness, and swelling.
