When patients experience angular cheilitis, it is acceptable to eat crab in moderation. Crab is considered a "cold" food, and even though it can be consumed, it is advised not to overeat to avoid other discomforts. Do not consume in excess. When angular cheilitis occurs, it is also recommended that patients eat more fresh vegetables and fruits, which can significantly aid in the recovery from angular cheilitis. During the day, make sure to drink plenty of warm water. Additionally, it is advised to apply some anti-inflammatory ointment locally on the affected area, such as erythromycin ointment or gentamicin eye ointment, which can be very effective in promoting healing. When experiencing angular cheilitis, patients may feel local pain; it is essential to maintain oral hygiene. (Please use medication under the guidance of a doctor)
