Hi @ralph13 - Welcome to Connect! I have not had nerve ablation but you have come to the right place. I'm sure there were people discussing this procedure earlier this year. It may have been in the Chronic Pain Group. I'm going to tag a few people who may remember further back than I go - @johnbishop, @mamacita, @grandmar, and @JustinMcClanahan. Are you having pain in both knees? If I remember correctly there were discussions of nerve ablation going on concurrently with some discussion of CBD Oil. Have you tried that or any other remedies?
