What should I do if my skin is ulcerated and oozing yellow fluid?

Clean the wound regularly, remove necrotic tissue and secretions, keep the skin clean, and maintain a dry wound to prevent further infection. Avoid scratching the affected area to prevent worsening of symptoms. Seek medical attention promptly. The doctor will prescribe appropriate antibiotics and anti-inflammatory ointments based on the patient's specific condition. Eat more foods rich in protein and vitamin C, such as eggs, lean meat, fresh vegetables, and fruits, to support the body's tissue repair.
