"Wasted trip"

After spending the night on the assessment ward my 2 year old granddaughter was discharged early hours of today saying we need to to wait for her blood results at home which they did. I phoned up today to find out what the results was and was told ahe must go back asap as ahe had a high inflammation markers amd needed treatment as soon as, i asked about my granddaughtera itp as was diagnosed in may this year to be told its not on her records she was ever r there, my son and daughter in law took her back to the hospital to be discharged a hour later saying there was nothing wrong with her.. 50 pound down on transport costs and a hell of a worry about my granddaughters health and actually do not know who to believe there as been told different things amd by the way she itp have photos ect to proof juat want to know whats going on as its a childs health at bay.. Very unhappy nan
