Nothing is more stressful than days and nights spent with chronic neck, knee, back, or spinal nerve pain. All those sleepless nights, tearful moaning, and being unable to work at moments are the worst parts of having chronic pain. Radiofrequency ablation can be a game-changer in terms of coping with pain. It can help relieve chronic pain, giving you life again and eliminating the need to take that hoard of pain medications or reducing the need for medication or other treatments.

What is RFA?

RFA – Radiofrequency Ablation, also named rhizotomy, is a procedure that uses electric current sourced from radiofrequency waves to destroy specific nerve cells by heat. It's much helpful in comforting chronic pain. The basic aim is to block or reduce pain signals reaching the brain. It is a much helpful treatment for delaying surgeries and improving functions.

It is commonly used to treat long-term and persistent pain conditions like spine arthritis, peripheral nerve pain, facet joint inflammation, sacroiliac joint inflammation, and neck, knee, and back pain. This treatment takes no or minimal time for recovery; it's a source of immediate pain relief.

History of Radiofrequency Ablation

Radiofrequency Ablation has been used for 18 years to treat cardiac arrhythmias and nerve-related chronic pain. Nikolai Bogduk developed this incredible pain comforting procedure to relieve chronic pain arising mainly from the facet joints in the lower back (lumbar). Radiofrequency waves target identified nerves around the facet joints; lumbar medical branches of the dorsal ramus of the spinal nerves. The intense heat affects the nerves, destroying their ability to send pain signals to the brain via motor neurons.

Lateral branch Nerves: The lateral ones transmit pain signals from the sacroiliac joint to the brain. The sacroiliac joint is found between the sacrum and the ilium.
