After the upper lip suddenly bulges, it feels that there is a lump in the person's position and the appearance of the lip becomes sharp, which may be caused by granulomatous cheilitis or periapical periodontitis.
1. Granulomatous cheilitis is a common cheilitis, the main symptom of which is swelling and hypertrophy of lips.
2. Dental apicitis is a chronic inflammation of the periapical tissues of teeth, which will affect the lips in severe cases and cause redness and swelling of the lips.
I suggest you go to the stomatology department in time to determine the cause and further treatment. In the meantime, you can pay attention to a light diet, avoid irritating food, eat more protein and foods with high vitamin content, and drink more water.
