"bewildered"

I was admitted for urgent m r angiography for short distance intermittent claudication.in left leg. After being I spent four nights on the ward and was ultimately discharged on the 25th of july 2o15 with no explanation when the 3 day procedure would take place. I did have a scan during this time but had already had one on my 1st appointment on Monday 13th July,my initial visit. I then had a letter from the Consulting General, Vascular Surgeon, which did not make any sense, but I waited and waited for an appointment to no avail. In desperation I phoned the secretary of the Consultant Vascular Surgeon who I had seen on my initial visit, and was admitted almost immediately. They were very sympathetic. The procedure was performed and I was discharged two days later. Would like some answers.
