As my readers will have read before I had great success with lumber facet joint injections for low back pain. I have never had facet joints injections in my cervical spine but nor have I had a nerve block in my lumber spine so it’s interesting to find out the difference between them both.
The cost is definitely different for these two injections with the facet joint ones coming out a lot more expensive.
To explain the difference with these two types of injections I will start with a facet joint injection which is a type of steroid injection that is administered to a very specific set of joints. Steroid injections directly into these joints of concern can help relieve both inflammation and pain in the neck or back. Several injections to different facet joints may be needed depending on the site of pain.
As explained by the Spine Institute of North America a local anesthetics, steroid
In a facet injection procedure, a physician uses fluoroscopy (live X-ray) to guide the needle into the facet joint capsule to inject lidocaine (a numbing agent) and/or a steroid (an anti-inflammatory medication). If the patient’s pain goes away after the injection, it can be inferred that the pain generator is the specific facet joint capsule that has just been injected.
A nerve block injection is also done using Fluoroscopy (live X-ray) to ensure the medication is delivered to the correct location. If the patient’s pain goes away after the injection, it can be inferred that the back pain generator is the specific nerve root that has just been injected.
