How long does it take for a pierced ear infection to heal?
Generally speaking, an infected ear piercing can heal within 3-10 days, depending on the specific circumstances. Detailed analysis is as follows:

If the symptoms of an infected ear piercing are mild, such as slight redness, swelling, pain, or minimal discharge, and the patient's immune system functions well, the infection can usually heal in about 3-5 days through proper care measures. These include cleaning the ear piercing area daily with normal saline, keeping the piercing dry, and avoiding contact with contaminants.
If local redness and swelling are more severe, or if there is pus discharge, this indicates a more serious infection. At this point, the earring should be removed as soon as possible, followed by cleaning the area around the piercing with an antiseptic solution such as povidone-iodine, making every effort to remove the pus. The healing process will take longer in such cases, possibly 7-10 days for a full recovery.
During the recovery period, it is important to maintain good lifestyle habits and ensure adequate sleep, avoiding late nights and excessive fatigue. Additionally, keep the area around the piercing dry and clean, and avoid touching or scratching the affected area with hands to prevent worsening inflammation or causing secondary infection.
