Itchy Bug-Bite Bumps in Children
Despite its name, papular urticaria is not true hives. It is an allergic-type skin reaction to insect bites, most often seen in children between about 2 and 10 years old. The bumps are itchy, last for days to weeks and tend to come back in crops.
What Causes Papular Urticaria?
Fleas, mosquitoes, bed bugs and mites are the usual culprits. A child who becomes sensitized to proteins in the insect saliva can react to every new bite, and sometimes to old bite sites. Pets are a common source of fleas.
Papular Urticaria Symptoms
- Small, firm, intensely itchy bumps, often in clusters or lines
- Common on arms, legs, and areas not covered by clothing
- A blister or crust in the center of some bumps
- Scratch marks and sometimes secondary infection
True hives are different: they are flat-topped welts that move and fade within a day. See hives vs bug bites.
Treatment
Find and remove the source: treat pets for fleas, wash bedding on hot, and consider a pest-control inspection. Topical corticosteroids, prescribed by a doctor, can calm the bumps, and a non-sedating antihistamine may ease itching. Keep nails short, and prevent new bites with long sleeves and approved repellents.
When to Call 911
Call 911 or go to the emergency room right away if your child has hives along with trouble breathing, wheezing, swelling of the lips, tongue or face, repeated vomiting, unusual sleepiness or floppiness, pale or bluish skin, or seems seriously unwell. Hives in a young child can be a sign of a severe allergic reaction.
When to See a Doctor
See a doctor if your symptoms last more than a few days, keep coming back, cover large areas, or interfere with sleep or daily life. The Hives Treatment Center in San Francisco, founded by Dr. Tiffany Young, is a dermatology practice dedicated to hives and related conditions, and is accepting new patients.
