Hello,even though this question is almost a year old I will answer it anyway.
For 16 years I've taken Lyrica for nerve pain. I also get cervical and lumbar rhizotomy once a year.
A rhizotomy is where they burn the nerves that causes the patients pain.
It's a very painful procedure but it's worth it because it last for 6 months to a year.
The procedure is done with IV sedation.
Hope this helps. Take care
