Sorted!

This exciting piece of kit is part of the Diagnostic imaging Suite at The alexandra Hospital.
Nice bit of kit here....
The "Procedure" is delightfully called a Fluoroscopic guided Hydro Dilation of the shoulder joint . (Right )
This was far less painful than the same procedure I had 13 months ago in my left shoulder, and the prognosis is excellent. 
So nothing to worry about really.
I am looking forward to a proper nights uninterrupted sleep now :-)
