It is very difficult to predict if the procedure will indeed help you or not. Generally speaking, the patients who have responded to repeated local anesthetic blocks will have better results. Generally speaking, this procedure is safe. However, with any procedure there are risks, side effects, and the possibility of complications. The risks and complications are dependent upon the sites that are lesioned.
Any time there is an injection through the skin, there is a risk of infection.
This is why sterile conditions are used for these blocks. The needles have to go through skin and soft tissues, which will cause soreness. The nerves to be lesioned may be near blood vessels or other nerves which can be potentially damaged. Great care is taken when placing the radio frequency needles, but sometimes complications occur. Please discuss your specific concerns with your physician.
