Hi mums, my 4 year old had an upper tract infection and had a high temperature I took him to A&E and they told me that. Now his temperature has started to improve a bit after few days but now he is refusing to walk and keep on telling me he has sore legs and can't put any weight on them. I took him back to A&E yesterday and they said it's due to the infection he has had. I'm just looking to know how long before he starts walking agian on his legs? And has someone else had this kind of experience. It's making me feel really sad to see him like this. Thanks
