Usually 60% of subjects will respond to steroid epidurals. However, in one study, if subjects were depressed, then on 1/5 cases responded. Why?

Comment – One thing I remember was a description of Thoracic Outlet syndrome where one of the chief features was resistant depression. First thought I had about the case of steroid epidural non-responders was that they were obviously more mutli- dimensionally sick with facet syndromes, Thoracic outlet syndrome, myofascial and rib pain syndrome, and associated insomnia. Second thought was since finding 20-25% of fibromyalgia cases are bipolar, that maybe this dimension needs handling before given shots. Someone in a mixed state -jumpy, irritable, tense and not sleeping is not going to feel any better with just shots. A common analogy to treating chronic pain is like peeling layers of an onioin to find there are many more layers underneath – treat with epidural and find the thoracic outlet, upper rib issues and myofascial pains. I give 2 thumbs down to present study because they did not bother to see what layers lay under the epidural non-responsive issues. Treated a back pain with a midazolam caudal just to find her ribs were impinging on one side iliac crest and needed treatment as well – could have had a SI joint or piriformis or thoracolumbar issues as well
