Hello, This is Suzfue46. I had radiofrequency ablations (also known as radiofrequency lesions or radiofrequency cauterizing) where an electrical current is past from the tip of the needle to nerves where the irritation is occurring. Mine were targeted at T10-T11. It disables the nerves from sending pain signals to the brain. I understand that the nerves eventually (in 6 months to 2 years) grow back and will need a further RFA. I did have a RFA on my S.I. joints which didn't help much. Every one is different so give it a try for a chance at relief if your doctor thinks it may help.
