Swollen Ear Canal: Common Causes, Symptoms and More

3Fungal Infections

While it is rare, a swollen ear canal may be caused by a fungal infection, which occurs when fungi like Aspergillus or Candida overgrow in the ear. It is more common in subtropical and tropical regions. Those who undergo an extended period of antibiotic use or practice a lot of water sports, such as surfing or diving, may also be at a higher risk. Weather conditions in the summer make people more prone to fungal infection as well. When this happens, your ear may appear red and swollen. You would feel relatively uncomfortable and itchy as well. Discharge may lead out of your ear. Common treatment options for fungal infections include ear drops, oral or topical medications, NSAIDs, acetaminophen, and certain home remedies. [3]
