does any body have experience of this and can tell me the symptoms? or their experience of this . am worried about my dd aged 3. she has been wakeing in the night crying and saying her knees hurt occasionally for the last six months, last week she had a really high temp. for 4 days - nothing else wrong ie sickness or throat infection, since then she is waking in pain every night, refusing to walk much, is whingy and constantly on the verge of tears - not herself at all. yesterday she said her knees hurt in the day which was the first time she had complained while awake. (sorry does that make sense?) today i took her to nursery in the buggy, as she has been crying whilst walking, and this afternoon we have had floods of tears and upset. she came to tell me she was hurting . i want to think that its attention seeking and a reaction to starting nursery, but something is niggling at me. took her to the emergency doctor on sunday, but he said temperatures cause aches and pains and to give her infant paracetamol. am i right to be worried?
