&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Acute Sinusitis (Acute Rhinosinusitis): Symptoms, Causes &amp;amp; Treatment&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Acute sinusitis, medically known as &lt;strong&gt;acute rhinosinusitis&lt;/strong&gt;, is a short-term inflammation of the sinuses &amp;mdash; the air-filled cavities located behind the forehead, cheeks, and eyes. When these spaces become inflamed and swollen, normal mucus drainage is blocked. As mucus builds up, pressure increases, leading to facial pain, congestion, and difficulty breathing through the nose.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Acute sinusitis is most commonly triggered by the &lt;strong&gt;common cold&lt;/strong&gt;. The majority of cases improve within 7 to 10 days without the need for antibiotics. However, if symptoms persist or worsen, a bacterial infection may develop and require medical assessment. When sinus inflammation lasts longer than 12 weeks despite treatment, it is classified as &lt;strong&gt;chronic sinusitis&lt;/strong&gt;.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;What Is Acute Sinusitis?&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;The sinuses are lined with a thin layer of tissue that produces mucus. This mucus normally drains into the nasal cavity. When inflammation occurs &amp;mdash; usually due to a viral infection &amp;mdash; the sinus openings narrow or become blocked. As a result:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Mucus cannot drain properly&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Pressure builds inside the sinuses&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Bacteria may multiply in trapped mucus&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;This leads to the characteristic symptoms of acute sinusitis.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Symptoms of Acute Sinusitis&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Symptoms often develop after a cold and may initially feel similar to flu.&lt;/span&gt;&lt;/p&gt;
&lt;h3&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Common Symptoms&lt;/strong&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Thick yellow or green nasal discharge&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Postnasal drip (mucus running down the back of the throat)&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Blocked or congested nose&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Facial pain, tenderness, swelling or pressure (often worse when bending forward)&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;h3&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Other Signs and Symptoms&lt;/strong&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Ear pressure or fullness&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Headache&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Toothache (particularly upper teeth)&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Reduced or altered sense of smell&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Cough, often worse at night&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Bad breath (halitosis)&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Fatigue&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Fever&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;It is important to note that coloured mucus does not automatically indicate a bacterial infection. Viral sinusitis can also produce thick discharge.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Causes of Acute Sinusitis&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;&lt;strong&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;Viral Infection (Most Common):&lt;/span&gt;&amp;nbsp;&lt;/strong&gt;&lt;/span&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;The majority of acute sinusitis cases are caused by viruses associated with the common cold. Viral infections inflame the sinus lining, leading to temporary blockage.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Bacterial Infection:&amp;nbsp;&lt;/strong&gt;&lt;/span&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;In some cases, blocked sinuses create an environment where bacteria multiply. Bacterial sinusitis is less common but may require prescription treatment if symptoms persist beyond 10 days or significantly worsen.&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Risk Factors&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Certain medical conditions and environmental factors increase the risk of developing acute sinusitis:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Hay fever or allergic rhinitis&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Recent upper respiratory infection&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Deviated nasal septum&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Nasal polyps&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Structural abnormalities inside the nose&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Cystic fibrosis&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Immune system disorders, such as HIV&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Smoking or exposure to second-hand smoke&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Air pollution&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Managing underlying conditions can significantly reduce recurrence.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Potential Complications&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Complications from acute sinusitis are uncommon but can be serious if the infection spreads.&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Chronic Sinusitis: &lt;/strong&gt;&lt;/span&gt;Acute episodes may develop into chronic sinusitis, lasting more than 12 weeks.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Meningitis: &lt;/strong&gt;&lt;/span&gt;A rare but serious infection of the membranes surrounding the brain and spinal cord.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Bone or Skin Infections: &lt;/strong&gt;&lt;/span&gt;The infection may spread to nearby bone (osteomyelitis) or skin (cellulitis).&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Vision Problems: &lt;/strong&gt;&lt;/span&gt;If infection spreads to the eye socket, it may cause swelling, double vision, reduced vision, or, in severe cases, permanent vision loss.&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Urgent medical attention is required if severe symptoms develop.&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Treatment for Acute Sinusitis&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;h3&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;1. Self-Care and Home Management&lt;/strong&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Most cases resolve without antibiotics. Recommended measures include:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Saline nasal sprays or rinses&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Steam inhalation&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Adequate hydration&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Rest&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Paracetamol or ibuprofen for pain relief&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Short-term use of decongestant nasal sprays (no longer than 3 days)&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;h3&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;2. Medical Treatment&lt;/strong&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;If symptoms persist beyond 10 days, worsen after initial improvement, or are severe, a GP may consider:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Antibiotics (if bacterial infection is strongly suspected)&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Intranasal corticosteroid sprays to reduce inflammation&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Antihistamines (if allergies contribute to symptoms)&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;In line with antimicrobial stewardship guidelines, antibiotics are prescribed only when clinically indicated.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Prevention of Acute Sinusitis&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;While not all cases are preventable, the following measures can reduce risk:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Wash hands regularly&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Avoid close contact with individuals who have colds&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Effectively manage allergies&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Avoid smoking and secondhand smoke.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Use a clean humidifier in dry environments&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Maintain overall immune health&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;When to See a Doctor&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Most people with acute sinusitis recover without medical intervention. However, seek advice from a healthcare professional if you experience:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Symptoms lasting longer than 7&amp;ndash;10 days&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Symptoms that worsen after initially improving&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Persistent fever&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Recurrent sinus infections&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;A history of chronic sinusitis&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;h3&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Seek Immediate Medical Attention If You Develop:&lt;/strong&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Pain, swelling or redness around the eyes&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;High fever&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Confusion&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Double vision or other visual changes&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Stiff neck&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;These symptoms may indicate a serious complication requiring urgent assessment.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Prognosis&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;The outlook for acute sinusitis is generally excellent. Most cases resolve within 10 days with conservative management. Early recognition of worsening symptoms and appropriate medical evaluation can prevent complications.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;In Summary&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Acute sinusitis (acute rhinosinusitis) is a common, usually short-lived inflammation of the sinuses, most often caused by viral infection. While symptoms can be uncomfortable, they typically improve with simple self-care measures. Persistent, severe, or worsening symptoms should be assessed by a healthcare professional to rule out bacterial infection or complications.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;If symptoms continue beyond 12 weeks, further evaluation for chronic sinusitis may be required.&lt;/span&gt;&lt;/p&gt;
