Introduction
Tiny, itchy bumps appearing densely on the lips are usually caused by conditions such as eczema, allergic dermatitis, or cheilitis. Patients should seek medical guidance and use medications accordingly. Besides these common causes, other possible factors include herpes simplex, hand-foot-and-mouth disease, and ectopic sebaceous glands. Patients should maintain a light diet and avoid spicy foods.
Small, itchy bumps appearing densely on the lips are usually caused by conditions such as eczema, allergic dermatitis, or cheilitis. Patients should seek medical guidance and use appropriate medications accordingly. Specific causes are analyzed below:
1. Eczema
When the skin around the mouth is exposed to external irritants or allergens, localized eczema may develop, presenting as small papules or vesicular papules on the skin surface, accompanied by symptoms such as itching and stinging. It is recommended that patients apply topical medications such as tacrolimus ointment or desonide cream under a doctor's supervision to alleviate symptoms.
2. Allergic Dermatitis
If a patient has recently consumed foods that are prone to cause allergies, an allergic reaction may occur on the lips, manifesting as red rashes or erythema, along with symptoms including itching, swelling, and warmth. It is advised that patients take antihistamines such as levocetirizine hydrochloride tablets or chlorpheniramine maleate tablets under medical guidance to relieve symptoms.
3. Cheilitis
Cheilitis is commonly associated with habits like excessive lip-licking or infections. Due to local irritation, papules appear on the skin surface, often accompanied by swelling, pain, and burning sensations. Patients are recommended to take medications such as azithromycin tablets or amoxicillin capsules under a doctor’s direction for treatment.
In addition to the common causes mentioned above, other possible factors include herpes simplex, hand-foot-and-mouth disease, and ectopic sebaceous glands. Patients should maintain a light diet, avoid spicy foods, and minimize local irritation.
