Similar to TENS physical therapy, radiofrequency ablation uses electricity to treat pain. First, the medical professional relaxes the patient with intravenous medication. Then they numb the neck with an anesthetic. The doctor inserts a thin needle into the skin and then transfers a microelectrode through the needle. That electrode receives a radiofrequency current to heat the surrounding nerve tissue. Radiofrequency ablation stops the treated area from sending pain signals and can last for up to a year.
