4yr old dd unwell Fri and Sat with high temperature - she was fine Sunday and yesterday. She has woken up and cried with pain when she went to stand up - that was 2 1/2 hrs ago. I have had to carry her about - she cannot weight bear at all. Can only think it is cramp as she had temp of 40 on Saturday and was v sweaty. Am getting her to drink as much as poss but earliest Dr Appt today is 5.30. Has anyone any ideas? Am so worried (A&E dept is hour drive, no parking and I have chronic back prob)
