Sinus infection, or sinusitis, is an inflammation of the sinuses and nasal passages. A sinus infection can cause a headache or pressure in the eyes, nose, cheek area, or on one side of the head.
Do not put anything inside, such as tissue or cotton to pack the nostril. Apply ice wrapped in a zip-lock bag or towel on the nose to reduce swelling and pain. You can do this for 15-20 minutes at a time, up to 3 times daily. Take a pain reliever or anti-inflammatory medication such as paracetamol or ibuprofen. Be sure to take these after eating something to reduce the risk of stomach irritation. If your nose is congested due to allergies or sinusitis, nasal decongestants, nasal sprays and antihistamines may be helpful. However, when you have taken these for more than 3 days but the symptoms persist, consult a doctor.
