We also thought my boys wrist was just a sprain. He fractured his Scapoid bone as his wrist was swollen on top and bottom but still had full function.
My point, just don't wait to long to get it looked at if the "sprain" is still hurting.
He's out 6-8 weeks, and he wasn't wearing wrist guards as he is supposed to....
Hope she heals fast
