What is a radiofrequency nerve ablation?

A radiofrequency nerve ablation is a medical procedure that doctors use to ease nerve pain, notes WebMD. The method involves the use of electrical current to heat up the area where there is the pain.

Doctors recommend radiofrequency nerve ablation for patients suffering from arthritic pain, neck pain and low-back pain, explains WebMD. The degree of relief patients receive depends on the cause and location of the pain. RFA is an effective method of treating some pain, with only minimal side effects that can include bruising and swelling at the area of treatment. Patients with bleeding problems or existing infections cannot receive a radiofrequency nerve ablation.
