"Sick patients"

I went in Westmead Hospital. They treated me, but then I had to return the following day because I was in pain with my stomach from a assaults I had a while ago and sharp pains in my head. I was weak, faint and nearly collapsed on the floor.  They told me that there was nothing wrong with me and I could go home. I was also told the doctors were coming to talk to me and then I could have some pain relief and they would keep me in overnight. Then they sent one of their sick patients home in pain.
