Boiler pressure guage

[Thirsty]

I have a Combi-boiler; which, given the weather, has been running almost continuously for the last week.

I've just noticed that the pressure guage needle is between 3 and 4 (4 is the highest); it's normally around 1-2. Should I be concerned about this? When I switched it off the needle dropped back down to 3 immediately.
