My leg hurts it fills like a deep cut uper right leg it only hurts there what is it?

Nerve Entrapement: Sometimes this might indicate pressure over one of the nerves supplying the thigh, giving the feeling of deep pain. I would suggest to see your doctor for assessment and further management

Nerve injury?: I can't say for sure. That type a localized pain makes me think there's some kind of nerve injury or neuroma or something. You can ask your physician to clarify what it is.
