I have had chronic low back pain for the last couple of years(bulging disc). The epidural steroid injections did not help at all. Back in February, at he pain clinic, they did a radio frequency ablation to the medial branch nerves in the facet joints. Two months after this procedure, I woke up pain free and have been for the last six months, with no percocet. My insurance did require that they do two different injections into the facet joints with lidocaine before they would authorize the ablation, which I thought was unnecessary and extremely painful. I can see one, but two? I hate mis-managed care.
