I had an injection on the eft side of my neck guided by imaging in a doctor's office in January 2021. It was a painful injection but it did help. The pain pretty much disappeared for a long time. I do get a headache on the left side of the head above the ear once in a while. I have stenosis in the cervical spine. Be careful doing neck exercises, you can aggravate the situation. I have pain in my lower back. I've had injections in the facet joints, both sides on two occasions. The second time they did not help. So, I tried RFA (radio frequency ablation) I think that made the pain a little worse. I'm going to try an epidural injection guided by imaging, next Monday for the lower back and the right foot.pain.
