Because of her age it is hard to determine if her reluctance to move/use all her fingers, etc., is due to an inability, or just extreme pain in that area. However, she is showing three of the five physical signs of a fracture or sprain--pain, swelling, loss of function (the other two being a crackling sound and bruising or bleeding into the skin at the site) so I would probably go ahead and have her see the doc and see if she needs xrayed. Otherwise, you're doing the right thing with the ice and motrin.
