Dryness and tightness of a membrane on the lips are generally caused by cheilitis or mucosal diseases. Cheilitis is a chronic inflammation occurring on the lips, associated with factors such as vitamin deficiency and nutritional imbalance, with primary symptoms including dryness and cracking of the lips. If patients suffer from mucosal diseases such as lichen planus, leukoplakia, or ulcers, pathological changes like white net-like patterns or spots may appear on the lip mucosa, causing lip pain. When the above phenomena occur, patients are advised to seek timely medical evaluation for accurate diagnosis and receive targeted treatment accordingly.
