Hives are itchy red bumps,
also known as wheals or welts. This is not uncommon in infancy amongst toddlers. Acute hives often come on after a food allergen exposure if indeed the infant is food allergic. And there’s normally and obvious cause.
So, if the child is egg-allergic and they eat scrambled egg, hives will typically come on around the
head and neck and elsewhere on their body. Hives that come on over weeks such as two to
three weeks often arise due to an infection. Here, you’ll find that antihistamines
are not very effective at controlling these and that they wax and wane – some days will
be worse than other days. And this arises due to an infection, sometimes
a very mild infection such as just a runny nose. Hives that come on for longer than six weeks, this
condition is known as chronic spontaneous urticaria. This is a very troubling condition
where the hives lasts for two, three, and in some patients even many more years. High-dose
antihistamines are required and indeed there are other medications for these patients.
And they need to be seen in expert centres.
