"Refused further checks"

I'm still in pain as I'm writing this,

Came to A&e with an abdominal pain, mainly on the lower right side.

Got to be seen by the nurse. They said to me I'm in a rush, can't see you for long. They literally saw me for less than 2 min. I was then called by the doctor, who listened to what I had to say, checked and saw that I was in pain. But decided that "We can't do an ultra sound today, but I can give you painkillers and discharge home"

I said to them I'm not happy and that the pain is still there and it could be anything.

I'm in pain, you guys should be checking what's wrong.

It's ridiculous.

I will try and avoid coming to this hospital anymore.
