Nasal polyps
Nasal polyps are swellings of the normal nasal lining that occur inside the nasal passages and sinuses (air-filled spaces behind the nose, eyes and cheeks).
They are typically pearly in colour and can vary in size. Each polyp is teardrop-shaped, and can look like a grape when fully grown.
You may not always know if you have nasal polyps because they can be difficult to see and don't always cause any symptoms.
Nasal polyps usually only causeproblems if they are large orgrow in clusters.
Symptoms can include:
If polyps block your sinuses, theycan cause a build-up of fluid thatmay become infected (sinusitis) . If this happens, you may have facial pain, toothache and a high temperature (fever).
The symptoms of nasal polyps can be very similar to those of more common conditions, such as a cold . However, colds tend to clear up within a few days, whereasnasal polyps usually won't get betterunless they'retreated.
You should see your GP if you have nasal symptoms that last a month or more.

This will usually involve an endoscopy (where a small tube with a camera at one end is inserted up your nostril) or a computerised tomography (CT) scan .
Nasal polyps can be difficult to get rid of permanently, but steroid medication can often help shrink them, and surgery to remove them can be carried out if medication doesn't help.
The main treatments are:
As polyps can grow back after treatment, including after surgery, you will usually be advised to continue using corticosteroid nasal sprays to help stop them returning quickly.
