Sinusitis Explained: Symptoms, Causes and Treatment

Sinusitis refers to inflammation of the sinuses, the small, air-filled cavities located behind the forehead, cheekbones and nose, most commonly occurring as a result of a viral infection such as a common cold. It is an extremely common condition, with acute sinusitis, meaning symptoms lasting less than twelve weeks, affecting a genuinely significant proportion of adults in the UK at some point each year.

Common symptoms include facial pain or pressure, particularly around the forehead, cheeks and eyes, a blocked or runny nose, reduced sense of smell, thick nasal discharge, headache, and a general feeling of being unwell. Symptoms often worsen when bending forward or lying down, and many people notice facial tenderness when pressing gently around the affected sinus areas specifically.

Acute sinusitis most commonly develops following a viral upper respiratory infection, when swelling and inflammation from the initial cold prevents mucus from draining properly, creating an environment where bacteria can occasionally develop into a secondary infection. Other contributing factors can include allergies, nasal polyps, a deviated septum, and, less commonly, dental infections that spread to nearby sinuses.

Chronic sinusitis, where symptoms persist for twelve weeks or longer, represents a genuinely different and more complex condition, often involving ongoing inflammation rather than a simple lingering infection, and typically requires a more thorough assessment and different treatment approach compared with the more straightforward, shorter-term acute form of the condition.

Most cases of acute sinusitis resolve on their own within two to three weeks without needing antibiotics, since the underlying cause is usually viral rather than bacterial. Treatment during this time generally focuses on symptom relief, including staying well hydrated, using over-the-counter painkillers for discomfort, and considering saline nasal rinses or decongestant sprays to help ease congestion.

Antibiotics are generally only recommended for sinusitis when symptoms are severe, worsening after initially improving, or lasting considerably longer than the typical viral course would suggest, reflecting current medical guidance aimed at reducing unnecessary antibiotic use, since research has consistently shown limited benefit from antibiotics for the majority of straightforward sinusitis cases.

For chronic or recurrent sinusitis that does not respond to standard treatment, a GP may refer patients to an ear, nose and throat specialist for further investigation, which can include a nasal endoscopy or CT scan to properly assess the sinuses, occasionally leading to treatments including nasal steroid sprays used long-term, or, in some cases, surgery to improve sinus drainage.

Anyone experiencing severe facial pain, swelling around the eyes, a very high fever, or symptoms that persist well beyond the typical timeframe expected for a cold should seek medical advice, since these can occasionally indicate a more serious complication requiring prompt treatment. For most people, however, sinusitis resolves without complication within a few weeks.

Pharmacies across Newcastle can offer advice and over-the-counter treatment for straightforward sinusitis symptoms, while GP practices can arrange further investigation or specialist referral for anyone experiencing chronic or recurrent symptoms that do not settle with standard initial treatment. Using a humidifier, particularly during drier winter months, can help some people with recurrent sinusitis by keeping nasal passages properly moist, potentially reducing how often symptoms flare up during the colder parts of the year specifically.

Most cases clear up fully within a few weeks without needing any specialist involvement at all. Avoiding air travel during an acute sinusitis flare-up where possible can help prevent additional discomfort too, since changes in air pressure during flights can worsen sinus pain considerably for anyone already dealing with active inflammation and congestion. It is a condition that, for most people, clears up well with nothing more than time and simple care.

Speaking to a pharmacist first often provides genuinely useful initial advice on managing sinusitis symptoms before deciding whether a GP visit is needed. Building this understanding genuinely helps most people manage the condition confidently without unnecessary worry or repeated GP visits. That kind of steady, practical confidence tends to make the biggest genuine difference over time.
