Thanks for answering Viv. All done I really don't know why I got myself so chewed up about it.
Oh, and thank you for the warning about the 'blues' I'd have got the shock of my life !
Hi Jood, you may well be having this done by now but it's nothing to worry about. They literally just inject the dye above your nipple. It doesn't particularly hurt. Look out for the blue wee and poo though. Made me and my friends and family laugh!!!!
