Sinusitis or sinus infection

Sinusitis or sinus infection is inflammation of the air cavities within the passages of the nose.
Sinusitis can be caused by infection,allergies, and chemical or particulate irritation of the sinuses.
Most people do not spread sinus infections to other people.

Sinusitis may be classified as acute sinus infection, subacute sinus infection, chronic sinus infection, infected sinusitis, and noninfectious sinusitis.

Sinusitis signs and symptoms include

• sinus headache,
• facial tenderness,
• pressure or pain in the sinuses, in the ears and teeth,
• fever,
• cloudy discolored nasal or postnasal drainage,
• feeling of nasal stuffiness,
• sore throat,
• cough, and
• occasionally facial swelling.
• Symptoms of a bacterial sinus infection include
• facial pain,
• pus-like nasal discharge, and
• symptoms that persist for longer than a week and that are not responding to over-the-counter (OTC) nasal medications.
• Sinus infection is generally diagnosed based on the patient history and physical examination.
• Bacterial sinusitis is usually treated with antibiotics. Early treatment of allergic sinusitis may prevent secondary bacterial sinus infections.
• Home remedies for sinusitis and sinus infections include over-the-counter (OTC) medications such as acetaminophen (Tylenol and others), decongestants, and mucolytics. Nasal irrigation can be accomplished with a Neti-pot or rinse kit (nasal bidet).
• Rare fungal infections of the sinuses (for example,zygomycosis) are medical emergencies.
• Complications of a sinus infection that may develop are meningitis, brain abscess, osteomyelitis, and orbital cellulitis.
• There are no fungal vaccines available to prevent fungal sinus infections.
