Sorry, Sandra is no longer active in our Forum. Sometimes you can get a reply if you leave a note or a message on the poster's (Sandra's) Profile Page.
If that is not successful I encourage you to begin your own thread, "Post a Question." Select a catchy title that is appropriate to your questions. I'd post it in this forum and include or Arthritis Forum too. Here's the link:

I have not heard of an RFA being used in your type of situation. I do know that it is being used more and more to treat pain in areas where it was never used before. It is a fairly safe procedure. I hear from many ppl that have experienced significant pain reduction, usually in the spine.
Have a long discussion with the physician that is recommending this procedure. Ask lots of questions, know the pros and cons! Educate yourself so you may make an informed decision.
Please begin a new thread - and keep in touch. I'll be very interested in hearing the outcome of your procedure.
Take Care - and Best of Luck,
