Ok... Flector is an NSAID (non-steroid anti-inflammatory), which is the same category of medication as ibuprofen. Norco is another name for Vicodin, which is one of the firstline opioids. Many opioids are not very effective in treating neuropathic pain (the kind you have), but Norco is a little different in this respect; it interacts pretty well with other medications used for treating neuropathic pain.

Gabapentin is an anti-seizure drug that has proven quite effective in treating neuropathic pain. It shouldn't be a problem for migraines, as it's sometimes used to treat them. It does carry a warning about increased suicide risk, so extreme care would be in order, but it is very effective in treating that kind of pain for a lot of people. Lyrica is similar to gabapentin, but more expensive (still under patent). Both gabapentin and Lyrica work fairly quickly for neuropathic pain; you should get relief with the first dose.

Anyway, your focus should still be on controlling the pain - not necessarily how (specific drugs). There are still many other options of long-lasting pain medications (up to 12 hours) before getting to fentanyl. Rrae is correct; once you start with the more powerful opioids, it becomes progressively more difficult to get off of them; they are usually used for people who will have chronic pain indefinitely. You don't want that at this point. Hopefully, yours will resolve.

Are you in a MMJ state?

There's no way to guarantee the pain will go away, but it should get better, though it may take some time. That's too bad about the anti-depressants - one of the reasons I mentioned amitriptyline is that in addition to helping chronic pain (particularly at night) it's also helpful in migraine prophylaxis, and has recently been found to help in neurogenesis (helping damaged nerves heal/regrow). Have you actually tried amitriptyline? (I'm not trying to be argumentative; it just seemed like a really good possibility/fit.)
