OK, I wandered down to A&E just after midnight - despite the waiting room being empty for a while, I was there until about 3am then admitted as an in-patient after x-rays. There was some talk about a fracture shown on them, but nothing in the notes.
After the results of the blood tests came back negative for septicemia (the discolouration had them nervous I guess) I was released just before 2pm, having been on two wards by then.
Top marks to the guy in A&E for using medical tape like duct tape to lash a sheet to a drip-stand to make a sling I could actually get my arm into (there was no way in hell either of the normal configurations would work due to restricted movement)
I'd just like to say how nice a couple of guys on the same ward were - one wrote childrens books and paid to get them published himself to help them get around the idea of death - which he gave away to hospitals and doctors he met, the other was a surgeon from another local kids hospital. Here's a virtual drink to Tony and Peter :-)
