There is not a lot your orthopedist can do for nerve pain - but has he done a post-op x-ray yet to determine that the hip is properly in place and healing? If not, it is typically scheduled anywhere from 2-6 weeks post-op depending on their protocol.
If everything looks good, you could ask for a prescription for gabapentin, which is sometimes used for nerve pain. My ortho tries to avoid this because there can be unwanted side effects.
