Jenni, that must have been absolutely horrendous with the radiographer, it would have been bad enough trying to explain to anyone just how impossible it was for you to get in such a position, let alone someone who couldn t understand what you was trying to say ! I had to have an MRI scan on my hands/ wrists and had to lie on a bed in the superman flying position for about 20 mins each one, put it this way I would never ever do it again if my shoulders were that bad, whatever the reason for one.
I sincerely hope putting off the knee replacement has nothing to do with financial cost, that seems a terribly long wait for the other surgery especially in your position.
