Just looked up catarrh which looks possible.

This is one site.

"Catarrh can lead to a number of problems, for example:

the need to continually clear the throat
the feeling of a lump at the back of the tongue
dry tickly cough
post nasal drip
other throat symptoms, eg snoring, bad breath, tonsilloliths, sore throats
If untreated, catarrh can persist for many years, and may be the cause of considerable distress, both to the sufferer and those around them.


How common is catarrh?
Catarrh is a common problem, affecting around 20% of the population.

Catarrh seems to be most marked in the 40 – 59 year old age group, with an incidence of around 15% of the general population, male and female. If the other associated symptoms are included, then the incidence of catarrhal symptoms in the adult population is over 50%. There is some evidence to suggest that these symptoms are predominantly conditions associated with polluted areas, with dust being one of the exacerbating factors. Also, a lifestyle associated with stress, processed food, an overweight population, alcohol etc., exposure to infections through living in a close society and an indoor lifestyle are also linked to catarrhal symptoms.
