The child has a hard lump on his leg

A hard lump on a child's leg may be due to skin allergy or bacterial infection, resulting in folliculitis.

1. Skin allergy: Children are relatively young and their skin may be relatively delicate. If the skin is irritated by contact with animal hair or pollen, hard bumps may appear, accompanied by itching symptoms. In life, if clothes made of poor materials are worn, allergic symptoms may also occur. Go to the hospital for an allergen test. Generally, you can take oral antihistamines under the guidance of a doctor. You can also apply cooling and antipruritic ointments. Try not to scratch with your hands, as secondary infection is likely to occur. Choose loose or pure cotton clothes to reduce friction on the skin.

2. Folliculitis: Folliculitis is a common skin disease. It may be caused by low immunity of children and obvious bacterial infection. Small bumps or nodules may also appear. Folliculitis is mainly an inflammatory skin disease with hair follicles involved. Redness or papules may appear in the center of the hair follicles, and it may be accompanied by obvious itching symptoms. You can take oral anti-inflammatory drugs under the guidance of a doctor, and you can also apply erythromycin ointment, which has the effect of inhibiting bacteria.

Pay attention to taking frequent baths to reduce the invasion of some bacteria and provide good skin care.
