"Angioplasty"

I have recently come out of Cheltenham Hospital after having an angioplasty. I asked for a pre med (sedation) for the procedure. As far as can see I didn't get this nor a local which I expected. I felt every thing that the surgeon was doing and it was very painful, no one seemed to be interested in how much pain I was in. So now looking at putting in formal complaint. I have had this procedure before at Southmead Hospital in Bristol so knew what to expect, but this one was nothing like the first one I must state that the staff on the day ward were brilliant though
