More about hives

Symptoms and treatments

Symptoms

  • swelling
  • itchiness

There are many possible triggers of hives, including:

  • allergens, like food or latex
  • irritants, like nettles or medicines

Treatment

There’s no cure for keratosis pilaris. It often gets better on its own without treatment.
