What should I do if my lips are swollen after biting them?

Nowadays, many people often have the habit of biting their lips. Although this is very bad, it has become a habit for everyone. There is really no way to improve it in normal times. In fact, making the lips look good is a relatively easy thing, but after the lips are swollen, you can apply some sesame oil, or use other methods to temporarily relieve it.

It is a temporary, localized, painless subcutaneous or submucosal edema. The main cause of the disease is type I allergic reaction caused by foreign proteins or drugs.

【Diagnosis points】

① It is more common in the loose connective tissue around the lips, more often in the upper lip than in the lower lip.

② The swelling develops rapidly and is obvious within 10 minutes. The edema area is bright and flushed, painless but with a feeling of distension, burning and itching. The swelling may last for several hours or may subside within 1 to 2 days.

③ Edema is most common in the upper lip, manifested as thickening and protruding upper lip, or limited to the upper lip-nose wing area. If it occurs on the tongue or palate, it may cause temporary language and eating disorders. Severe edema can spread to the floor of the mouth and throat, causing breathing difficulties.

【Treatment principles】

① Quickly identify and eliminate allergens.

② Apply calamine lotion on lips to protect skin and relieve itching. ③ Use antihistamines and corticosteroids if necessary. ④ Pay attention to cases where the disease spreads to the oropharynx and causes breathing difficulties, and perform preventive tracheotomy if necessary.
