Medical staff don't care what they do to you

Had a knee replacement on 11 March 2019. 3 days in I was moved form High Care (Where they gave me 3 very strong injections (for what I don't know) then I was moved to a semi private ward (Section D) where they put you on a bedpan and leave you on it for 1/2 hour that your back get spasms. Then the Physiothe****** never made me walk in High care and that day she made me walk for the first time. The pain was so bad and I could hardly move, when returning to my bed, she leaves me in the doorway and I pass out (falling backwards and with my bum on the door stopper that was sticking out about 5 cm ) leaving me with a ****** bum. I put in a complaint and had to email 3 x before someone contacted me, but could not give me any information on who authorized the injections and what happened, she said someone else will investigate and come back to me. I am still waiting. I am NEVER going back to that hospital, the people there don't care about you. When I got discharged I waited 45 min for a wheelchair (if I could walk out of there I would have)
