"Been held waiting for 4 hours for my girlfriend..."

My girlfriend was kept in the hospital over night on the 10th may 2016 due severe pain in her ovary area that was due to a cyst rupturing on her ovaries and the day after on the 11th may 2016 after blood tests and scans she was told they couldn't find any thing wrong and was told she could go home this was at 13:00 on the 11th may 2016 the doctor is just writing out her discharge letter and 5 hours later we are still sat there and no letter has been written and nobody is aware of what is going off it is ridiculous how they just say one thing and don't follow it through I wouldn't recommend the hospital to anyone
