Sinusitis is swelling of the sinuses, usually caused by an infection. It's common and usually clears up on its own within 2 to 3 weeks. But medicines can help if it's taking a long time to go away.

Check if you have sinusitis

Sinusitis is common after a cold or flu.

Symptoms of sinusitis include:

pain, swelling and tenderness around your cheeks, eyes or forehead
a blocked nose
a reduced sense of smell
green or yellow mucus from your nose
a sinus headache
a high temperature
toothache
bad breath
Signs of sinusitis in young children may also include irritability, difficulty feeding, and breathing through their mouth.

A pharmacist can help with sinusitis

A pharmacist can advise you about medicines that can help, such as:

decongestant nasal sprays or drops to unblock your nose (decongestants should not be taken by children under 6)
salt water nasal sprays or solutions to rinse out the inside of your nose
You can buy nasal sprays without a prescription, but they should not be used for more than 1 week.
