Sinusitis is the inflammation and pain associated with the sinus passages, leading to excess mucus or blockages. There are two main types of sinus problems, acute and chronic.

Acute sinusitis

This is when sinusitis occurs for up to four weeks and is usually caused by a previous viral infection which has damaged the sinus tissues. During this time the body fights the infection or antibiotics are given and the tissues eventually heal and the sinusitis goes away.

Chronic Sinusitis

This is when sinus problems continue for longer than 12 weeks and for some just becomes a part of their life they have to learn to 'put up' with. Symptoms include:

• Nasal congestion from excess mucus production
• Sinus headaches (usually a pressure in the forehead or around the eyes)
• Post-nasal drip (mucus 'dripping' down the throat)
• Facial Pain (due to sinus cavities under cheeks, eyes and in forehead)
• Fever (due to low level but chronic infection)
• Halitosis or 'bad breath'

Putting up with these symptoms can be very difficult indeed and many sufferers will be using nasal decongestant drugs and sprays on an almost daily basis.

Allergic Rhinitis

This is another form of chronic sinus problems and rather than being triggered by bacteria or a viral infection, the inflammation in the sinuses is caused by environmental allergens such as pollen, dustmites, pollution or moulds which irritate the nasal passages and trigger excess mucus production. Symptoms can be very similar to those for chronic sinusitis but there may be more sneezing and wheezing and in some it causes or exacerbates asthma.
