Chronic sinusitis and rhinitis explained

Rhinitis and sinusitis: what's the difference?

Rhinitis means inflammation of the lining of the nose, causing symptoms such as sneezing, a runny or blocked nose and an itchy nose. Sinusitis, more accurately called rhinosinusitis, means inflammation of the nose and the connected sinuses, causing blockage, a reduced sense of smell, facial pressure or pain, and thick nasal discharge. The two overlap and often occur together, which is why doctors increasingly talk about rhinosinusitis. Problems are called chronic when they last a long time — for sinusitis, generally more than twelve weeks. Acute sinusitis, by contrast, usually follows a cold, lasts a few weeks and settles on its own. Understanding which pattern you have helps guide what will actually help.

What causes long-term nose and sinus problems

There are several common causes. Allergic rhinitis, triggered by things like pollen (hay fever), house dust mites, pets or mould, is very common and causes sneezing, itch and a runny, blocked nose. Non-allergic rhinitis can be triggered by cold air, strong smells, smoke or changes in temperature. Chronic rhinosinusitis often involves ongoing inflammation, sometimes with soft swellings called nasal polyps that block the nose and dull the sense of smell. Infections, a deviated (bent) nasal septum, smoking and air pollution can all play a part. Because the causes differ, a runny, itchy nose from allergy and a blocked, pressured nose from chronic sinusitis with polyps may need quite different treatment, even though both feel like a permanently troublesome nose.

Self-care that genuinely helps

A lot can be done without prescription medicines. Rinsing the nose with salt-water solutions, using a spray or a rinse kit, helps clear mucus and allergens and soothe the lining, and is a mainstay of managing both rhinitis and chronic sinusitis. Steam inhalation may ease congestion for a short time. If allergy is the trigger, reducing exposure helps — for example keeping windows shut during high pollen counts, using dust-mite covers, and avoiding known triggers. Stopping smoking makes a real difference, as smoke inflames the nasal lining. Staying well hydrated keeps mucus thinner. These simple measures are often the foundation of treatment, and for milder problems they may be all that is needed alongside occasional over-the-counter remedies.

Medicines and when to see a specialist

When self-care is not enough, several treatments help. Steroid nasal sprays are a first-line treatment for both allergic rhinitis and chronic rhinosinusitis; used regularly, they calm the inflammation and reduce blockage, and are safe for long-term use for most people. Antihistamines help the sneezing and itch of allergic rhinitis. Salt-water rinses are often combined with these. Decongestant sprays give quick relief but should only be used briefly, as using them for more than about a week can make congestion worse. If symptoms persist despite proper treatment, if there are nasal polyps, or if problems keep coming back, a GP may refer to an ear, nose and throat specialist for assessment, a nasal examination or scans, and occasionally surgery to improve drainage.

Warning signs and living with it

Most sinus and nose problems are a nuisance rather than a danger, but some symptoms need prompt attention. Seek urgent medical advice for swelling or redness around an eye, eye pain, changes in vision, a severe headache with a stiff neck, confusion, or a very high fever, as these can rarely signal a serious complication of sinusitis. See a GP for symptoms only on one side of the nose, persistent blood-stained discharge, a lump, or ongoing loss of smell, so these can be checked. For most people, though, chronic rhinitis and sinusitis are long-term conditions that can be managed well with a steady routine of salt-water rinses, regular steroid sprays and trigger avoidance, allowing them to keep symptoms to a minimum and protect their sleep and daily life.
