My 5.1 year old boy (only child) has been suffering from very high temperatures and delusions specifically at night. He has a cold and is also on antibiotics for an ear infection. Two nights ago he had an episode where his body jerked uncontrollably. Today he awoke with painful legs and can't walk and can only stand if on tip toes. We went to the doctors today who seemed to think that maybe Samuel is play acting for attention. Although I'm obviously open to the fact that this suggestion may be the case it is very unlike him as he normally gets on with things until he is really ill and, having often doubted him in the past and ended up in A&E a couple of times, I'm worried to ignore it. He complained of sore legs when we lifted him for a wee in the night and he is still not walking now - is that a long time for a 5 year old to keep something like this up consistently? I'd really appreciate your opinion
