Re: Radio Frequency Lesioning...
My mom and I have both had this done -- I had mine about a month ago. My mom has had five or six of them. Supposedly they last 6 months to two years -- in her case it has been closer to six months, but it does the trick pretty well for that particular pain. However, the nerves grow back and they fray and grow multiple connections, meaning the chance of effectivity decreases with each successive procedure.
I had mine a month ago -- after a week, I felt better than I had in a long time, and had about 3 solid weeks. Five nights ago the pain came back full force, so I have some concerns about this. My medial nerve block was succesful as well...but this rhizotomy (same thing) didn't seem to do the trick.
Basically, this isn't a cure. Realistically even if it works, at most you would get 10 years out of it, and I have a feeling the real average is much less. If you use that time productively to build up your core and your health, you may be able to very positively influence the rest of your liife.
The procedure itself is cake, especially if you've had medial nerve blocks. The hardest part is when they inject the local anesthetic -- that always hurts as the liquid expands in your muscle tissue. Beyond that they just validate if you feel certain things -- although your age and condition have a lot to do with it. Being young (25), everything was where it "Was supposed to be" according to the doctor, and they didn't have to retry any of the six sites. On my mom it has taken them a try or two on each site before they get the right spot. If they offer you a general anesthetic, I'd take it if for no other reason than to prevent compulsive jerking -- it sort of numbs your mind to the process.
