Wow, I could literally write over 10000 words on just the neurophysiology of the meso-limbic system alone and not necessarily cover XXXXXXX Blum
J Addict Res Ther. 2014 ; 5: . doi:10.4172/2155-6105.0000. (now there is one depressing paper! It says that everything in your brain is wired up for misery after the suboxone and you'll be better but it will take 2 weeks to be off of it).
Ok... I cannot comment directly on your particular situation, or diagnose, nor treat without directly being there.
and first, the article implies that brain chemistry is going to be very messed up by long term narcotics especially suboxone and this predisposes to severe depression. While anti-depressants work, they take longer than the time to reset the brain by being off suboxone and they do nothing for 2 weeks. Furthermore, the increased energy that some/most anti-depressants give are a known risk for suicide. In this context, inpatient supervision (brief) is best. Giving an anti-psychotic along with the anti-depressant is next best. And getting supervision by immediately going to an ER in the context of thought disorder and suicidality is really necessary. The thought processes of the depressed person are not normal, and are unreliable.

Next is about pain.
Yeah, there's way more than 10,000 words
http://dmm.biologists.org/content/6/4/889.full
(don't read it, it's really too hard for me and I'm an expert in the field; just realize there's a lot of reasons why the pain can be chronic).
Several signs can point to particular features of pain. There is the direct cause of pain both it's process and the underlying problem. Most people already know where the pain is coming from in a general sense (nerve injury, inflammation, infection, etc.). AND... there are particular reasons why the pain is worse on a given time frame. Often it is an inflammatory condition on top of a non-inflammatory injury. Steroids help ONLY in this narrow context. Then there's one I should care about,
http://www.ncbi.nlm.nih.gov/pubmed/0000 (he generally goes by WAXMAN), in which the spine is really upset and there's like an epileptic fit in the spine which doesn't feel good, and has a lot of LOCAL back pain.
There's particular neurophysiological ways to approach this.
now.
So, there is the overactivity of the spine itself and the muscles. They can theoretically ping-pong back and forth with activation. Interrupting the XXXXXXX is helpful. Any nerve pill will be quite good and quick. These include the anti-epileptics gabapentin and pregabalin (no relation), also carisoprodol. Maybe muscle relaxants like flexeril. But directly stimulating the nerves overwhelmingly can also be helpful.
(so, if I start with the neurophysiology, then saying "a warm shower with the water beating down on the area and mild movement, ideally massage by someone else during the shower", then that sounds more reasonable. If I started by saying that, people don't give it serious consideration). This can be done now.

Then, there is also the counter irritant effect
https://en.wikipedia.org/wiki/Counterirritant
this is broadly helpful on a lot of the mechanisms involved in that very hard article. Some of the mechanisms include over stimulation like above, stimulation induced killing specifically of pain nerves, modulation of the factors that wind down pain. Also changing the ionic surroundings of the nerves through sodium and pH can modulate their activity.

Now doesn't that sound better than "mustard plaster"?
but, today, one could freshly grind a LOT of mustard seed in vinegar, (warm, not hot) enough to cover gauze pad and apply to the area for 30-45 minutes.

So, in general, one would look at acute safety and often recommend emergency psych eval---short term stay.
Modulation of nerve activity through direct stimulation, anti-epileptics and counterirritants.
thats before even thinking narcotics.
