Why Has My Corner of the Mouth Been Sore for a Year, Both Before and After?
Common causes include herpes simplex virus infection and angular cheilitis. In such cases, it is very necessary to seek medical attention promptly, as doctors can provide targeted treatment plans based on specific conditions.
Herpes Simplex Virus: This viral infection is one of the common causes of mouth corner ulcers. It is contagious and can spread through direct or indirect contact. During onset, patients usually feel local itchiness and pain, and sometimes blisters may rupture. For this situation, doctors may recommend applying medications such as Acyclovir cream to the affected area to relieve symptoms. In severe cases, oral medications such as Valaciclovir hydrochloride tablets can also be used as adjuvant therapy.
Angular Cheilitis: Malnutrition or vitamin deficiency may lead to angular cheilitis, an inflammatory reaction of the oral mucosa. Symptoms include dry, cracked lips and peeling skin. To improve this condition, compound vitamin B tablets and zinc gluconate granules can be taken under a doctor's guidance to supplement the body's required trace elements and minerals, thereby promoting healing.
Other Possible Causes: Eczema may also cause mouth corner ulcers, especially in damp and hot environments or when exposed to allergens. Symptoms of eczema include local redness, swelling, and papules. Symptoms can be improved by avoiding allergens and taking antihistamines such as Loratadine capsules or Chlorpheniramine maleate tablets as prescribed by the doctor to relieve itchiness. In daily life, maintaining good hygiene habits is very important. Pay attention to cleanliness, avoid staying up late, and focus on a diet of light and easily digestible foods, such as millet porridge and pumpkin porridge. If symptoms worsen, seek medical attention as soon as possible to obtain professional medical advice and treatment. Through these measures, we hope to help you better cope with the problem of mouth corner ulcers.
