Ear infections aren’t just for children—about **20% of adults** still experience them. Bacteria and viruses can affect anyone, and those with weaker immune systems need to be especially alert. Recognizing early signs is crucial since, as the article notes, **“early detection is key to swift treatment and relief.”**

One of the first signs is **itchiness inside the ear canal**. While it may seem minor, constant itching can signal an infection. If ignored, it often worsens. Consulting a doctor at this stage can help prevent complications.

Another warning sign is **redness inside or outside the ear**. The article explains, **“this redness is a clear sign of inflammation and should not be ignored.”** Any unusual discoloration should be treated seriously and checked by a healthcare professional.

The most common and often most painful symptom is **discomfort or ear pain**. It can start as mild aching but may progress to a heavy, full sensation. Pain can intensify when touching the earlobe or tragus and, in some cases, radiate to the **face, neck, or head**. Ignoring it risks worsening the infection.

In short, watch for itchiness, redness, and pain—three key signs that an ear infection may be developing.
