If you have non-allergic rhinitis, there's a risk you could develop further problems.
These can include problems caused by having a blocked or runny nose, such as:
The inflammation associated with non-allergic rhinitis can also lead to further health conditions, such as:
Nasal polyps are fleshy swellings that grow from the lining of your nose or sinuses (the small cavities above and behind your nose), which are caused by inflammation of the membranes of the nose, and sometimes as a result of rhinitis.
They've also been linked with an increased risk of other health conditions, such as asthma, that develop later in life.
Nasal polyps are shaped like teardrops when they're growing and they look like a grape on a stem when fully grown. They vary in size and can be yellow, grey or pink. They can grow on their own or in clusters and usually affect both nostrils.
If nasal polyps grow large enough, or in clusters, they can:
Small nasal polyps can be shrunk using steroid nasal sprays so they do not cause an obstruction in your nose. Large polyps may need to be surgically removed.

Sinusitis is a common complication of rhinitis. It's where sinuses become inflamed or infected.
The sinuses naturally produce mucus, which usually drains into your nose through small channels. However, if these drainage channels are inflamed or blocked (for example, because of rhinitis or nasal polyps), the mucus cannot drain away and it may become infected.
Common symptoms of sinusitis include:
Symptoms of sinusitis can be relieved using painkillers, such as paracetamol, ibuprofen or aspirin.
However, these painkillers are not suitable for everyone, so make sure you check the leaflet before you take them. For example:
Speak to your GP or pharmacist if you're unsure.
Antibiotics may also be recommended if your sinuses become infected. In cases of long-term sinusitis, surgery may be needed to improve the drainage of your sinuses.

Middle ear infections (otitis media) can develop as a complication of non-allergic rhinitis.
Rhinitis can cause a problem with the eustachian tube at the back of the nose. If this tube does not function properly, then fluid may accumulate in the middle ear (behind the eardrum) and become infected.
There's also the possibility of infection at the back of the nose spreading to the ear through the eustachian tube.
Symptoms of a middle ear infection can include:
Most ear infections clear up within a couple of days, although paracetamol or ibuprofen can be taken to relieve pain and a high temperature. Antibiotics may also be prescribed if your symptoms persist or are particularly severe.
