Yes, it looks like your pain is in the genitofemoral nerve distribution. This is where I have my pain, as this is the nerve that was damaged by my spermatic cord stripping surgery. I think you should pursue the following treatment options:
Step One: Visit Dr. David C Chen in Los Angeles or Dr. Bruce Ramshaw in Florida (depending on which one you're closest to.) They will likely suggest a laparoscopic genitofemoral neurectomy. This may very well eliminate your pain.
Step two: If this is unsuccessful, find a pain specialist in your area who performs Dorsal Root Ganglion stimulation. This has a great chance of eliminating or reducing your pain.
Step three: If the DRG stimulation does not work, find a pain specialist in your area who can implant a peripheral nerve stimulator in your groin. This will provide constant electrical stimulation to your genitofemoral nerve, and possibly greatly reduce your pain.
Step four: If none of the above 3 steps work, then you will likely have to live with the pain. But more than likely, one of the three above steps will help you.
