The best thing to do is for her to see a doctor to pinpoint exactly what is wrong.
Your story does seem to fit as to why she's in pain. Fingering hard and fast can result in bruises (purple tint), rub burns (pink tint) and bleeding (ripped tissue from exessive rubbing or scratches from fingernails).
She could give it time to heal. But, again, a check with the doctor is her best bet.
Hope this helps and best of luck to you!
