"Wrongly diagnosed"

Went to a&e with dislocated knee seen by junior doctor who had it xrayed told it was badly sprained and bruised splint put on knee and given crutches. Couldn't use them so was given a zimmer frame and sent home and told to come back on the Monday for physio. I was back before then because as l came downstairs the knee buckled and the other one popped. Back to a&e where l was in a queue of about 6 people all been sick and vomiting.l was taken to a treatment room where the same junior doctor saw me. Of course l asked for a more senior doctor,after another xray it conspired that l had ripped the tendons and muscles from both knee's. I'm also a dialysis patient so was moved to the Freeman, where l had the op on my knees 13/1/18 l have been here until 30/3/18 and have been told I'm going to NESEC for rehab tomorrow as l live in Northumberland l have to be transfered back up there. I'm hoping that it's just a short stay and I'm moved to the Walton unit in morpeth ASAP. By the way every time I've been to NESEC I've caught the novo virus.
