Ouch, poor Oprah! I would gently clean her wound with warm water and antiseptic soap. Keep the wound clean and dry, and monitor it for signs of infection. If you see redness, swelling, warmth to the touch, or pus, then it is infected and she will need to see the vet for antibiotics to treat it. It sounds like she could have some separation anxiety, and it getting upset in her crate. You can get a pheromone diffuser called DAP that helps dogs with anxiety and pair that will a DAP pheromone collar that releases pheromones when in contact with her skin. If these methods do not help her, then I recommend having her seen by a vet to discuss the use of anti-anxiety medications. Best of luck, I hope this helps and enjoy your new dog!
