How do I know if I've got it?

If you've got glandular fever, you'll have a:

• Sore throat
• Swollen glands (in your neck, under your arms or round your groin)
• Feeling of being tired and unwell
• Headache
• Fever
• Rash (sometimes)

If you have these for more than 3 days, call the doctor's. If you've still got a bit of fever after your sore throat's gone away, and you feel exhausted, call the doctor as well.

He or she will do a blood test to see if it's glandular fever, though it doesn't always show up positive immediately. Several other diseases also make you feel like this but only glandular fever shows up in the test. If you're feeling tired all the time but don't have the fever, sore throat etc, click here.
