"I felt completely dismissed"

I went to A&E recently after a fall. I had a swollen/bruised wrist and hand as well as a minor head injury.

The first nurse I saw was thorough, ordered an x-ray and CT and even took me there. Waited a while (which is expected) and was finally back in the waiting room after 3 hours.

I then however waited another 2 1/2 hours for my results only to be rushed to dismissal. I was told x-ray and CT normal, rest your concussion and come back if anything gets worse, and discharged immediately. 

What I'm unhappy about it that I have broken this wrist before, exact placement and all, and the proper procedure for this specific fracture is a fracture clinic referral for another x-ray in 2 weeks as it doesn't always show up immediately. That didn't happen - I felt completely dismissed.
