GP said he does have it but not to worry too much... he's going to keep an eye on it himself and if he thinks it's getting worse over the course of the next year he'll refer us to a paed. He doesn't think it will need surgery but if it does then the earliest they operate is 2 years apparently. I'm happy with his opinion but there are other good GP's in his surgery that I can ask for a second opinion at any stage.
