How you prepare

By Mayo Clinic Staff

To determine if you're a good candidate for radiofrequency neurotomy, your doctor may perform a test to see if the nerves commonly targeted by the procedure are the same nerves responsible for your pain.

This test involves injecting a small amount of numbing medication into the precise spots where the radiofrequency needles will go. If your pain significantly lessens, radiofrequency treatment at those spots may help you.

Before the procedure, you should:

  • Avoid chewing gum or using tobacco products on the day of the procedure
  • Avoid using deodorants, lotions or perfumes on the day of the procedure
  • Use clear liquids to take any medications up to two hours before your procedure
  • Arrange for someone to drive you home
