Stings cause painful red bumps right away. Most of the time, the pain is better in a couple of hours. The sting could keep swelling for 24 hours. If your child was stung many times, your child may vomit or have diarrhea, a headache, and a fever. This is because of the large amount of venom from the stings.
Stings can also cause an allergic reaction.
If your child is allergic, your child may find it hard to breathe or swallow. Your child could pass out or get hives. You should call 911 or your doctor right away if this happens. Look for the stinger. If there is a little black dot in the area of the sting, the stinger is still in the skin.
