Dm is pushing me to take ds (9) to a&e. He was hit worth a rock around 4ish and I have been told it started to go black instantly although this has since spread. They're is also a bruise forming on the other side of his finger. Wwyd? Is it an a&e job or a Docs in the morning job? Or do I leave it altogether? Ds said it feels like it has a heartbeat and it's very tight to the point where he can't bend it.
