Lip infections are chronic, non-specific lip infections such as dryness, peeling, cracking, oozing, crusting, and lip discomfort, but they are prone to recurrence. The formation of labyrinthitis is related to a variety of factors, the most common of which are chronic and repeated irritation, especially chronic conscious or unconscious lip biting, lip licking, and lip tearing, which can repeatedly or aggravate the clinical symptoms of labyrinthitis. The manifestations of labyrinthitis are partly dry and flaky, and partly oozing from the lips, with yellow fluid oozing and partial formation of blood crust. Some of the symptoms are swelling of the lips and itching of the lips, which are usually associated with allergies. There is also a relationship between labyrinthitis and the climate, as labyrinthitis tends to flare up in the fall and winter months, mostly related to the dry and cold weather in the fall and winter. You should visit the oral mucosa department promptly when you have recurring lip infections. It is important to pay attention to strengthening the care of the lips to reduce the discomfort of the lips when lip infection strikes. You should correct the bad habits of lip biting, lip licking and lip peeling. Try to consume less spicy and stimulating food, quit smoking and drinking, eat a balanced diet, and go to the oral mucosa department for regular checkups.
