Just came back from going in the dreaded machine!! 3rd one in a year, never again, i must have put on weight since last one, had to fold my arms in to fit in, when moving me up and down my arms were sliding on the walls of the machine. They put my head in a brace covering my face !! So noisy, even with ear plugs. Also done my neck this time, wouldn't it be funny if it was my neck causing all these problems? After all these years? Seeing consultant September, will let you know outcome.
