Midnight - I saw someone at Guys who was dreadful, and someone at St Thomas' who was wonderful....however I can't remember either of their names. When you get your referral letter tell me the names and I will be able to tell if it is either of them! Sorry to be pretty rubbish in helping otherwise.
Midnight/Flying Fig there is definitely a gastro theme on this page. As THC says eds and gastro problems can go hand in hand. Pain, bad wind, vomiting are all things my ds has been affected by off and on since birth, and he is not really badly affected gastro wise.
Ihatecbeebies - Welcome and jump in!
Ellie - Prof Grahame and others speculate that eds and bjhs are the same thing, just that those dx with eds are more severely affected. I think it is most useful to think of the conditions as one, with varying degrees of severity and a variety of symptoms.....it seems to me that no eds sufferer has the same group of symptoms as any other. As THC says, they do like their boxes, so cross dx does rather confuse the medical professional

The Brighton and Beighton scales are also both critised by Prof Grahame and others, as they are relied on too heavily by less knowledgeable people. They focus on a small number of joints, yet we know that which joints are affected by hypermobility and which are "normal" can vary widely between patients. Both my ds and I have a confirmed dx of eds, a history of dislocations and subluxes, and a variety of other symptoms related to the collagen...mitral valve prolapse, migraines, gastro effects, miscarriage, etc. My ds is profoundly affected in his spine, shoulders and hips....but not so in his fingers, wrists and elbows, so he scores lower than me on the Beighton scale, and he is affected far worse than I. I have also stiffened up, mainly due to damage sustained, so I wouldn't score as highly now either....just 6/9. As with many things, a little bit of knowledge is not necessarily a helpful thing. If a medic relies purely on these scales, they would miss many, if they carried out a full clinical examination, they would be making the dx. I read and interseting article, in the Guardian I think a few years ago which talked about the issues in the rheumie community about missed dx, incorrect dx and weaknesses of the B and B scales.....would anyone like me to try and find it again???? I can try.
THC we got the arch supports in the post, I know I was taking a punt, but they seem to fit really well, and he is trying them out, and seems to be finding them comfortable. The gp ruled out Reynauds, as she said it had gone on too long for it to be that. We will see what happens. He is in a bad way at the mo, lots of shoulder pain, woke up with a sublux in his right shoulder this morning, now crippled with knee pain...and being very, very very grumpy! 
Hope everyone is well today. Sorry about the long post.
