Catarrh is a build up of mucus in an airway or cavity of the body - It usually affects the back of the nose, the throat or the sinuses (air-filled cavities in the bones of the face). It's often temporary, but some people experience it for months or years. Catarrh can be a nuisance and may be difficult to get rid of, but it's not harmful and there are treatments available.
Catarrh can lead to a constant need to clear your throat, feeling that your throat is blocked. Blocked or stuffy nose that you can't clear, feeling of mucus running down the back of your throat. Persistent cough, headache or facial pain, reduced sense of smell and taste. Crackling sensation in your ear and some temporary hearing loss
Treatments for catarrh include using a saline nasal rinse several times a day, Decongestants, antihistamines or steroid nasal sprays, Taking sips of cold water when you feel the need to clear your throat – constantly clearing your throat may make things worse. Catarrh will often pass in a few days or weeks as the condition that causes it improves.
