I picked my 6yr old up from school today and he was holding his arm by his side. He told me he and another child had fallen over while playing and the other child had fell on his arm. School just sent home a bump letter so I rang them to ask if he had used his arm all afternoon to be told he had done his work. He has hurt his right arm and he is left handed so this doesn't help at all. We decided to take him to a&e as his hand was very swollen and mottled. A doctor examined him and said it was just bruising. He's been joke for approx 2 hours. I've given him calpol and he's still not using his arm and wincing and crying every now and again. Should I take him somewhere to get a second opinion? I don't want to waste a&es time but I'm concerned he's not using it. He's not a mardy child. And normally bounces right back after hurting himself.
