Like Cymbalta? My doctor gave me that last year and I tried to keep taking them for a week to see if I could build up a tolerance, but they were so horrible that I had to quit, I was too sick to get out of bed unassisted. I tried them again a few months later and the same thing. But SSRI's make me violently ill too. Projectile vomiting.
Cymbalta is a SNRI. TCAs (tricyclic ADs) have been used for some types of back pain/referred pain/opioid resistant pain. Though they generally don't have great side effects, so if you've had trouble with SSRIs/SNRIs then they might not be for you. Still something you should possibly broach with your doctor if you are having trouble managing the pain.

Right now a nice demerol drip would be nice. I had that for my colonoscopy and I was happy all day. Just give me one of those beer can hats filled with demerol.
For some reason, I don't picture a beer-can-hat of demerol going over well with the FDA/DEA and scheduling departments

Thing is, my back doesn't hurt, I have referred pain, I guess that's what they call it, the pain is in my tailbone area (in the muscles) and down my legs and into my feet. My spine feels fine.
What did they find on the imaging, do you have stenosis of the intervertebral foramina or sciatica? If that's too personal, I understand :) Lots of nerve pain is opioid resistant. The only effect that opioids have on that kind of pain is sedation, which doesn't really alleviate the pain--It just knocks you out. That is why opioids are /supposed/ to be used with such caution in the case of chronic pain, bone pain, nerve pain, etc. Though how things are supposed to work and how some doc's proscribe are two entirely different stories :(

Yeah, the percoset either just takes the edge off the pain or has no effect that I can tell. I mostly take it for my stomach pain, it seems to help that more than anything. And I am so sick of pills! My doctor told me one woman had just come to him that had been treated by a pain doctor and was taking 9 percoset a day! More than half of one makes me itch like crazy and vomit. How can people get addicted to this stuff?
Yeah these pain clinics are becoming a big problem in the US, especially the eastern parts of the midwest (cause we don't have good heroin) and the south. Its unfortunate and I'm not really sure what the solution needs to be.
The itching and GI symptoms are common side effects of opioid analgesics. Its mediated through Mu-opioid receptors. If the percocet work for you pain though, let your doc know they are working, but you are having trouble with the side effects. Generally with opioids if there are side effects but good pain control your doc can add an agonist/antagonist (different opioid receptor action) that can alleviate side effects. Nalbuphine is used for this.
If you have poor pain control though and side effects or side effects with pain control, but sedation--they should really switch the opioid (there is a lot to choose from). Sometimes lowering the dose of an opioid can still get you analgesia w/o side effects, but the rule of thumb is to just switch opioids as there are many and the body's response to them varies greatly between individuals.
On top of that the problem with some of the opioids like vicodin (Hydrocodone) is that the parent drug itself isn't analgesic and requires metabolism by the liver to a biologically active opioid to produce analgesia (hydromorphone in the case of hydrocodone). The problem is that a significant portion of people lack the enzymes to produce, or sufficiently produce, the active analgesics.
Percocet (oxycodone) is a bit of an enigma. Supposedly oxycodone itself is analgesically active--Though it is metabolized to oxymorphone, which is active. Despite what some people will claim to you, no one is really sure whether it is the oxycodone or oxymorphone that provides the majority of the analgesic effect (both are Mu receptor agonists). It stands to reason though that since percocet or oxycodone literally doesn't work for some individuals that metabolites of the drug have a significant role to play in alleviating pain. So again, if it isn't working make sure to let your doc know and they can try one of the many, many other opioids available.

Like one of our anasthesiologist lectures on pain meds (opioids and non-opioids) was fond of saying: "It takes work to get addicted to a opioid". The side effects, like you've pointed out, are generally pretty horrible. The receptors and wiring are there in our brains (VTA, nucleus accumbens, VP wiring and all that jazz), but it actually takes an effort for incentive learning and maintenance to really "code" those addictions into our brains.
