Redness in Ear
Ear redness can affect the outer ear (pinna), ear canal, or surrounding skin, often signaling inflammation or infection. This visible symptom may be accompanied by pain, warmth, swelling, or discharge. While some causes are minor and resolve quickly, persistent or severe redness requires medical evaluation to prevent complications and ensure proper treatment.
⚠️ Seek Immediate Medical Care For:
- Redness spreading rapidly beyond the ear
- High fever with ear redness
- Severe pain and swelling
- Red streaks extending from ear
- Facial swelling or paralysis
- Confusion or altered mental state
- Pus or foul-smelling discharge
- Redness after ear injury
Definition and Overview
Redness in the ear, medically termed auricular erythema, results from increased blood flow to the area due to inflammation, infection, or other causes. The redness may be localized to a specific area or involve the entire ear. The pattern, distribution, and associated symptoms help determine the underlying cause and appropriate treatment.
The ear's exposed position makes it susceptible to various environmental factors, infections, and skin conditions. Redness can affect different parts: the outer ear (auricle or pinna), the ear canal, behind the ear, or the surrounding skin. Understanding which area is affected helps narrow down potential causes.
