My little boy (4 years 6 months) has been complaining of back pain for about 4 days. I've also noticed him sitting awkwardly, as though he can't get comfortable (especially leaning over to his right side when sitting in the car seat). He's had a bit of a cold this week, but nothing major. No temperature or anything like that. He has some development delay and is unable to tell me whether he's done something to it. Tonight it seems to have really bothered him. He kept lying on the floor and trying lots of ways to get comfy, then cried about it so I gave him calpol. He insisted on going to bed at 6.20 (so unlike him) and then woke very upset at 7.50.
Any ideas what could cause back pain in such a young child? I have anxiety and my mind is going through the worst case scenario. Think I'm going to try and get a gp appointment for tomorrow.
