nigel,

I'd do LOTS of homework on that procedure before undergoing it. And I would certainly seek other opinions.

Generally speaking, in my humble opinion, attempts in this category may carry more "risk" than reward. These doctors certainly mean well, but if it results in increased pain...you are left proverbially "holding the bag".

It is difficult because as you mention, we are all looking for the "magic bullet". Unfortunately, it may not exist.

Maybe somebody with some more actual knowledge of this technique will chime in??

From an article I read on PRF.....

"Use of RF treatment for the purpose of sympathetic blockade has the advantage over surgical resection, phenol or alcohol neurolysis because of being more selective and thus causing fewer complications.

PRF is a relatively new technique where short bursts of RF energy are applied to nerve tissue. It is suggested to be a minimally neurodestructive alternative to RF heat lesions, because of a potentially better risk/benefit ratio

However, clinical advantages and mechanisms of this treatment are still unclear. In none of the published reports, neurological side effects
or complications with PRF have been mentioned but it should certainly share some of the complications of conventional PRF such as epidural, subdural, or subarachnoid injection and trauma to the intervertebral disc, spinal cord and exiting nerve roots due to needle misplacement as well
as infection"
