Hi LittleBean-- yes, to the vet. Maybe fur mites but whatever the cause, toenails shouldnt be bare like that. And she cld b relieving the itch and irritation by running around etc. to use her toes. Its possibly not pain, but itch. If mites, they dont go away by themselves but they are easily treatable.
Also, ask the vet or vet tech to show you how to look at the toenails to see if they are too long. It's a physical stress on the paw toes when the nails grow out too far, and from your photos they need trimming. The points are sharp and too long past the pink of the quick. The nail grows out kind of like a tube and when it changes shape to look like an overhang of single sided nail, thats the point at which you can safely trim. You can see the change-point even in a dark nail. You still need a bunny vet to look at the nails and fur, though.
Congrats to you for being alert and asking questions, to say nothing about taking fotos!
