Post traumatic neuropathies are not uncommon following severe crush injuries like you have described.
Medications such as Neurontin or Tegretal may help but would require long term use. If the nerve is trying to regenerate then possibly giving it a full year for the sensation to improve is also an option. During the year you can be on the medication which may help with pain.
Injections of absolute alcohol have been use but this will result in permanent numbness of the lower eyelid, side of nose, cheek and upper lip on the affected side.
Finally, surgery may be required to severe/destroy the nerve closer to its origin

Thanks for your input. I have already had surgery two try and freeze the nerve and kill with alcohol but unfortunately the sensation keeps coming back. I have had the nerve traced as far back through the orbit where the surgeon tried to obliterate the nerve by removing a section.
Unfortunately within a couple of months the feelings returned again. It seems that I heal to well and the nerve keeps on repairing. My surgeon has agreed to try and obliterate the nerve but after this attempt I think they have run out of options.
Thanks and Regards
