Radiofrequency ablation (RFA) is a medical procedure in which radiofrequency energy is used to generate heat in order to destroy tissue. It is often used to treat chronic pain, such as back pain or cancer pain.
During the procedure, a healthcare provider inserts a thin needle into the skin near the source of the pain (typically a nerve). The needle is equipped with a small electrode that emits radiofrequency energy, which is used to heat up the nerve in the area surrounding the electrode. The heat causes the cells in the nerve to die, which can reduce or eliminate the pain signals being sent to the brain.
RFA is generally considered to be a safe and effective treatment for chronic pain. It is typically performed on an outpatient basis and can provide relief from pain for several months or even years. However, like any medical procedure, RFA carries some risks, including the risk of infection, bleeding, and nerve damage.
