Ceartict naves? As injury problem?

It seems like there may be a typo in your question. Did you mean to ask about "cervical nerves" or "nerve injuries"?

If you are asking about cervical nerves, these are the nerves that originate from the spinal cord in the neck region and control sensation and movement in the arms, shoulders, and neck. Damage to these nerves can result in pain, weakness, or numbness in these areas.

If you are asking about nerve injuries in general, they can occur due to trauma, repetitive stress, or underlying medical conditions. Treatment for nerve injuries may include rest, physical therapy, medication, or in severe cases, surgery.

Please provide more information or clarify your question so I can provide a more accurate answer.
