What should I do if my mouth is twitching?

Under normal circumstances, "chapped lips" refers to swollen lips or the appearance of cracks, which may be caused by factors such as weather conditions, ultraviolet (UV) exposure, spleen and stomach deficiency, allergies, or infection with the herpes simplex virus. It is recommended to seek timely medical evaluation to determine the underlying cause and receive targeted treatment. Specific analyses are as follows:

1. Weather Conditions

Dry and cold weather can lead to skin dehydration. Insufficient moisture may result in dry, cracked, and swollen lips. It is advisable to drink adequate water and use lip balm regularly to moisturize the lips, which helps relieve symptoms.

2. UV Exposure

Prolonged exposure to UV radiation may cause sunburn on the lips, manifesting as swelling, redness, and pain. It is important to apply sunscreen regularly and avoid extended periods in direct sunlight to prevent discomfort.

3. Spleen and Stomach Deficiency

Long-term picky eating habits may lead to spleen and stomach deficiency, resulting in malnutrition. Deficiencies in nutrients such as vitamin B, iron, and zinc may increase the fragility of lip tissue, leading to dryness, cracking, and swelling. Maintaining a balanced diet and ensuring sufficient nutrient intake supports overall health.

4. Allergies

Allergic reactions after using products such as lipstick or lip balm may also cause lip swelling or a stinging sensation, possibly accompanied by itching. Under medical guidance, medications such as loratadine tablets, cetirizine hydrochloride oral solution, or chlorpheniramine maleate tablets may be used for treatment.

5. Herpes Simplex Virus Infection

Viral infections may cause lip swelling or ulcers. For example, herpes simplex virus infection can lead to cold sores, characterized by swollen, painful lips with blister formation. Treatment under medical supervision may include topical acyclovir cream, valacyclovir hydrochloride granules, or acyclovir capsules, which aid in recovery.

Maintaining healthy daily habits and drinking sufficient water help preserve skin moisture balance. Additionally, keeping the local skin clean and hygienic can prevent infections and worsening of symptoms.
