What You Need to Know About Otitis Externa Ear Infection
Summary
Otitis externa, commonly known as swimmer's ear, is an infection of the outer ear canal. It's often caused by water remaining in the ear after swimming, creating a moist environment that aids bacterial growth. Typical symptoms include itching inside the ear, pain when touching the ear, and drainage from the ear canal. Treatment usually involves antibiotic ear drops, such as ciprofloxacin, used twice daily for 7-10 days.
What Is This & Why It Matters
Otitis externa is an infection affecting the outer part of your ear canal. It often happens when moisture gets trapped inside your ear, making it a perfect place for bacteria to grow. While it's not usually serious, it can be quite uncomfortable and annoying. Recognizing and treating it early can help you feel better faster.
What You Should Do
- Use prescribed antibiotic ear drops as directed by your healthcare provider.
- Keep your ears dry by using a shower cap or earplugs when showering or swimming.
- Gently dry your outer ears with a towel after any water exposure.
- Avoid inserting anything into your ears, like cotton swabs, which can worsen irritation.
- Follow up with your doctor if symptoms do not improve within 48 hours of starting treatment.
- Practice good ear hygiene to prevent future infections.
What You Should NOT Do
- Do not use over-the-counter ear drops without consulting a healthcare professional.
- Avoid submerging your ears in water until the infection clears up.
- Refrain from scratching or poking inside your ears with fingers or objects.
- Do not ignore persistent symptoms thinking they will resolve on their own.
- Avoid sharing towels or other personal items that may have come in contact with infected ears.
