Hi Kimi,   Rhizotomy RF uses electromagnetic energy field with very high frequency radio waves (400,000 cycles per second.) These radio waves are used with a knife like instrument or needle - depending on the exact proceedure you have - to burn the nerve. This is a temporary solution because the nerves may grow back. Some patients get relief for a few months, to a year.     If your doctor isn't able to help you, it may well be time to consult a Migraine and headache specialist. It's important to note that neurologists aren't necessarily Migraine and headache specialists. Take a look at the article Migraine and Headache Specialists - What's So Special? If you need help finding a Migraine specialist, check our listing of Patient Recommended Migraine and Headache Specialists.   I know how easy it is to feel as if you've tried everything out there, but there are so many medications that can be used for Migraine and headache prevention that it's literally impossible. You can find a list of potential Migraine and headache preventives in Migraine preventive medications - too many options to give up!   Good luck Nancy
