How to treat glandular fever | NHS

See a GP if you have:
a very high temperature or you feel hot and shivery
a severe sore throat
swelling either side of your neck – swollen glands
extreme tiredness or exhaustion
tonsillitis that isn’t getting better

These are glandular fever symptoms. You don’t usually get glandular fever more than once.

Glandular fever mostly affects teenagers and young adults. It gets better without treatment, but it can make you feel very ill and last for weeks.

You should feel better within 2 to 3 weeks. Some people may feel extremely tired for months.
Try to gradually increase your activity when your energy starts to come back.
Glandular fever can cause your spleen to swell. For the first month, avoid sports or activities that may increase your risk of falling, as this may damage it.
