@golfer18 Did you ask the doctor what an ablation is? From my understanding, an ablation destroys something that is malfunctioning as a way to remove it. A transformational injection would be to introduce a steroid to reduce inflammation as a temporary treatment for pain.

A radiofrequency neurotomy is an ablation of a nerve. This link gives more information. It does say that it can treat pain in buttocks, but not below the knee.

Your doctor is the best one to explain his choices in your treatment. Can you send him a question on a patient portal?
