"I went to the A&E department after an assessment..."

I went to the A&E department after an assessment over the phone with 111 when they told me to go straight away there. It was 4 pm. At 5.10 a nurse saw me and asked me lots of question to tell me: you will be seen shortly. I was seen at 6.40. I asked for a scan because of my problem. They gave me blood test and I waited until 8.20 when the doctor told me: you need a scan but the scan is not closed sorry. They asked me to stay overnight but I replied that I wanted to go go back home to rest and come back the day after but they said: you will lose the priority for the scan, sleep here and tomorrow you will have a scan. I waited and at 00.45 they finally found some accommodation for me for the night... The day after they told me to wait and at 12 when people were having lunch they told me there was no slot available for me for the scan so they told me to go home, spend the weekend and come back on Monday. Conclusion: I waited there 21 hours for nothing! Now I am happily at home with my pain still there and still worried.
