The skin becomes red, swollen, itchy and can be painful. These are the most common symptoms. Sometimes bites cause an allergic reaction. Bites can become infected by scratching. Look out for a rash or swelling that gets worse instead of better. If this happens, see a doctor.

Call your doctor immediately if you notice any of the following symptoms:

the person has been stung by many insects at the same time

a rash or swelling that gets worse instead of better

if the site is red, tender and swollen

headache

dizziness

nausea (feeling sick)

pains in the chest

choking or wheezing

difficulty breathing.

These may be symptoms of allergy and can be life-threatening if the victim goes into shock. See a doctor immediately or dial 999 for an ambulance.


What does a bite look like?

There will be one or more swollen red bumps on the skin. In the middle, you will often see a small hole, which might have the insect's sting sticking out of it.

If you wake up in the middle of the night having noticed a painful or itchy lump, check to see if other parts of the body are affected. If there is only one bump, or four or five of them close together, you have probably been stung or bitten. Fleas often bite four or five times in the same area so you may find a couple of these clusters on your body.

Some children's diseases can also cause bumps and red, swollen skin. If in doubt, consult your doctor.
