I suspect that you have a sinus infection which has extended to the soft bones of the nose. Sinus infections often start with common cold symptoms( runny nose), the bacteria/virus then gets into the sinuses. The pain you have around the forehead are could be from frontal sinus infection.
A painful nose is from infection until proven otherwise. The bridge of the nose if made of cartilages, which can become infected. Another possibility is that you have a polyp inside the nose that is now inflammed. Either case you most likely will need antibiotics.
For now, you can try taking sudafed( if you don't have a reaction to sudafed) to decrease sinus pressure.
I hope my advice is helpful. If so, please click "ACCEPT" so I can get credit for my work.
thanks for the reply, all mostly cleared now and nose no longer painful - that was the weirdest bit - I thought my wife had maybe punched me in the night! Cleared up on it's own after a few days.
