Brief summary

The purpose of this study is to compare two methods of giving epidural steroid injections for nerve pain in the arm that comes from the neck. An epidural steroid injection can be given in two different ways, either in the back of the spine within the neck or in the neck next to the nerve root going to the arm. Both are standard medical treatments. The investigators would like to see how effective these treatments are, and if there are any differences in effectiveness or safety between these two routes.

It is a well-validated tool for health status measurement, and for health quality-of-life in cervicogenic radicular pain. The EQ VAS records the patient's self-rated health on a vertical visual analogue scale where the endpoints are labeled 'The best health you can imagine' (100) and 'The worst health you can imagine' (0).
