Well, I'm back from the hospital. Weighed and BP taken: 160/100 -> 139/86 after 5 mins chilling out - I'm glad my GP taught me that trick! Then a 25 minute wait to see someone I've never met before who didn't even introduce himself, and nipped out partway through to check something with the consultant I was expecting to see. However my calcium levels are just the low end of normal, and my vitamin D levels are a little low, but then it has just been winter so they're not worried. Tick, vg, come back in 6 months to have calcium levels checked again, oh and we'll book you a bone density scan too and see if that's changed, and if all is well we'll discharge you at that point.
All a bit anti-climactic!
