From the Guidelines
For an enlarged lymph node below the left ear with an infected ear piercing, the recommended treatment includes oral antibiotics such as ciprofloxacin or levofloxacin, as these are effective against the most common pathogens, including Pseudomonas aeruginosa, S aureus, and S pyogenes, as noted in the study by 1. The treatment should also involve cleaning the piercing site twice daily with saline solution or mild soap and water, and applying an antibiotic ointment like bacitracin or mupirocin to the infection site. Some key points to consider in the treatment of infected ear piercings include:
- Auricular perichondritis and perichondrial abscess typically occur in the first month after piercing, especially during warm-weather months, as mentioned in the study by 1.
- The lymph node enlargement is a normal immune response to the nearby infection and should resolve as the infection clears.
- Warm compresses applied to the area for 15 minutes several times daily can help reduce pain and promote healing.
- If symptoms worsen (increasing redness, swelling, pain, fever above 101°F, or pus discharge), or if there's no improvement after 48-72 hours of treatment, medical attention should be sought immediately.
- It is also important to note that earrings can become embedded in the earlobe, and if gentle probing fails to locate an embedded earring, a small incision under local anesthesia may be necessary to locate and remove the earring or backing, as described in the study by 1. The infection likely occurred because ear piercings create open wounds vulnerable to bacteria, particularly Staphylococcus aureus and Streptococcus species, which can enter the piercing site from unsterile conditions or touching with unwashed hands, highlighting the importance of proper aftercare and hygiene in preventing such complications, as discussed in the study by 1.
From the Research
Lymph Node Enlargement Below the Ear
- An enlarged lymph node below the ear can be a sign of an infection in the ear, such as an infected ear piercing 2.
- The infection can be caused by bacteria such as Pseudomonas aeruginosa and Staphylococcus aureus, which are common causes of ear infections 2, 3.
Treatment of Infected Ear Piercing
- Treatment of an infected ear piercing typically involves removing the earring and administering antibiotic therapy 2.
- Topical antibiotics such as acetic acid 2%, aminoglycosides, polymyxin B, and quinolones with and without corticosteroids are commonly used to treat ear infections 3.
- Oral antibiotics may be indicated if there is evidence of cellulitis or if the patient has a compromised immune system 3, 4.
