A salty taste in the mouth - why?

[LaTrucha]

For the last few days at the back of my mouth and throat I've constantly had a really salty, slightly sour taste.

Does anyone know why?

I'm sure it's nothing serious, it's just annoying as I can't taste things properly and it's slightly unpleasant.

A bit of a tickly throat too, but no cold or anything has developed and it might not be connected.

I recently discovered something called 'pine mouth syndrome' which can leave a bitter/metallic taste for up to two weeks after eating pine nuts. Very unpleasant and not everyone is affected. Lots on internet about it and Which Magazine are currently gathering info.
