"Misdiagnosis again"

Went on Sunday evening with my 7yr old daughter after she injured her leg after falling off a low zip wire. Told it was sprained, go home don't rest it and getting her walking. 24hrs later daughter still in pain and unable to put foot down. Back to minor injuries same nurse reassured my husband just a sprain and keep up pain killers and get her walking on it. He had suggested an X-ray but was told not needed. Yesterday (Thursday) both concerned, A&E Winchester, X-ray severe break to her tibia, would have needed pinning if she was an adult, 6 weeks full plaster....4 days later. Outrageous. Never again.......we should have been told it wasn't a minor injury and sent to A&E straight away.....
