Whether it is electricity, freezing, or radio wave, these methods are all the same. they are designed to "cut/kill" the nerves that are causing the pain. I have had nerves cut (all of the 2nd branch and part of the 1st branch of he trigeminal nerve on the right side of my face. I think, though I could be wrong, that these procedures are not a permanent fix to the pain. I think most doctors/anesthesilogists are saying the relief can last up to 6 months. You might think this is a waste of time, but it is not. If you do get one of these procedures and get relief, then you may be closing in on a permanent fix for your pain problem. I say this because if you get relief, you KNOW what nerves are causing the pain. Always keep looking for a solution. I got about a month's worth of relief from my procedure. I was able to get a deep brain stimulator a year or two later. It cut my pain meds in half, and I was much more comfortable!!! They are making progress on chronic pain and controlling it, so what's not available right now might be available in the not too distant future!!! Good luck everybody!!!!
