Im English so its deifinitly grey for me guys. Cyclops, good luck with the surgery. Hope its not too painful. These stories of trips to the toilet sound horrible and I fear im not far from them myself.
PN certainly seems to be a horrible condition and as so many of you have said it is not understood by friends and family. The best way I have heard someone try and explain it to a non sufferer was try imagining a toothache that would never go away.
