If you've already responded well to diagnostic injections, the facet denervation procedure has a good chance of long-term relief from back pain. It might take up to three weeks for you to feel any benefit, but about half of cases can expect relief from symptoms for between three months and one year.

Do nerves grow back after denervation?

Radiofrequency denervation isn't a cure. The damaged nerve endings usually slowly grow back and the pain may return. If the treatment works for you, it may reduce your pain for between six months and two years.

Does denervation hurt?

Radiofrequency facet joint denervation is a minimally invasive procedure and serious side effects are rare. You may experience local bruising and discomfort and may feel sore for up to one or two weeks. This is normal, and is usually due to muscle and nerve irritation.
