Teen DS (13) has had pain in his lower back and possibly hip since yesterday. He kicked a ball and when his leg went out straight something "went" in his lower back/hip, he then fell over on his back and this seems to have made it worse. He has pain in his lower back and down one leg so I'm not sure if it's an issue with his back or hip. There is no bruising or mark on his back. He was worse this morning but is now up walking but can only weight bear on his toes on the affected side. I've had to keep him off school. He's not in agony or distressed, just painful when he's on the move and the pain is down his lower back and one leg.
I always have this dilemma in situations like this- should I leave it and it will probably be fine? If I leave it, am I potentially ignoring something serious by not getting it checked out? The paediatric a&e near us is very good (we have only been once before) but at the same time it's not a place we would want to visit unless necessary. Any thoughts?
