What causes intermittent pain in the outer ear contour?

Generally, episodic pain in the outer ear contour may be caused by cold exposure, pressure-induced strain, external otitis, auricular zoster, or perichondritis of the auricle. If discomfort occurs, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. Detailed analysis is as follows:

1. Cold Exposure

When the ear is exposed to cold environments, blood vessels constrict and spasm, stimulating nerves and causing paroxysmal pain, which can ease with warmth. Wear earmuffs promptly for warmth, apply a warm towel gently to the outer ear, and avoid continued exposure to low temperatures.

2. Pressure-Induced Strain

Prolonged use of tight earmuffs, headphones, or sleeping on one side can lead to soft tissue strain in the outer ear, impairing circulation and resulting in episodic pain. Remove tight ear devices, adjust sleeping posture to avoid ear compression, and gently massage the outer ear to improve blood flow.

3. External Otitis

Bacterial infection of the external auditory canal causes inflammation, leading to radiating, progressively worsening paroxysmal pain in the outer ear, often accompanied by itching and discharge. Follow medical advice to use ofloxacin ear drops, cefradine capsules, and hydrogen peroxide solution, and avoid digging the ear with hands.

4. Auricular Zoster (Herpes Zoster of the Ear)

Infection of the auricular nerve by varicella-zoster virus causes paroxysmal, needle-like pain, followed later by blister formation. Under medical guidance, apply acyclovir cream, take valacyclovir tablets and mecobalamin tablets, and keep the auricular skin clean and dry.

5. Perichondritis of the Auricle

Bacterial infection of the auricular perichondrium leads to inflammatory stimulation, causing severe paroxysmal pain in the outer ear, along with redness, swelling, and fever. Immediate medical attention is required. Follow medical instructions to use cefuroxime axetil tablets, dexamethasone injection, and levofloxacin hydrochloride ear drops. In severe cases, surgical incision and drainage of the perichondrium may be necessary.

In daily life, protect the ears from cold and avoid cold stimulation; choose loose-fitting ear devices to reduce pressure; maintain ear hygiene and prevent traumatic infections; seek medical help promptly if pain recurs frequently to identify the underlying cause.
