My gf accidentaly scratched my vagina really bad 2 nights ago. It still hurts to walk, sit down, and pee. Is there anything I can do? Orajel?

No to oragel! Sorry, missed the scratched part, that degree of trauma needs to be looked at, and a bit more care b/w you and your girl friend. That degree of pain could be related to infection from the finger nails or whatever did the trauma. See the doc.
Possible infection. If your symptoms are that severe, then you may want to see your ob/gyn to rule out an infection from the scratch.
