My husband had nerve ablation for his broken sacroiliac joint pain. He could not have surgery due to health issues. The ablation gave him total pain relief after a couple of weeks. It has been nearly one year and he is still pain free. He also had nerve ablations on his lumbar spine which was also totally successful. I think it matters where placement of the ablation and his Dr said it is more difficult to get the sacroiliac. We had to pay for the sacroiliac ablation because it is still considered experimental. It was worth the cost for pain relief.
