The fentanyl patches ( some of them anyway) were notorious for not sticking or not sticking as well as they should until recently, when most all of the manufacturer's remade the design of the patch, so that most of them now look like a piece of tape, with the dosage written on them. I am assuming that you are a male.......if that is the case, did you remove the arm hair or chest/back hair before applying each patch? If not, that is probably one of the biggest reasons why they did not stick. Also where you put the patch makes a huge difference in whether or not it will stick.
The other issue with the meds not working for very long may be one of the dosage not being strong enough. Whenever you start a new medication, the dosage is usually at the low end of the dosage range from a previous med, this is due to cross tolerance issues, so the doctor starts you on a lower dose of the new medication to see #1, if you will get pain relief, and #2-to make sure that you aren't going to have too many negative side effects. The dosages usually need to be titrated up some to get the right amount of pain relief and a minimum of side effects such as sedation/respiratory issues.
As far as not noticably getting any pain relief from the methadone/opana combination-it may be that the doses are too low for you , or it may simply be that you don't realize how much pain relief the meds are giving you. It happens to alot of chronic pain patients- we think that a med isn't working as well as it once did , and decide to talk to our doctors about changing them, or go off them completely only to find that the medication was working far more than we thought it was.
As our bodies adjust to a medication or a combination of medications, our bodies tend to experience or adjust to the side effects, but we also loose that feeling that we often have when we start a new medication- where we have a noticable feeling of pain relief..
It happens to everyone who has been on meds for any length of time, after you have been on them for awhile, you don't get that feeling that you got when you first started them, so we tend to think they aren't working any more.
I wonder why you aren't on any nerve/neuropathic type pain medications such as Lyrica or Neurontin, Topamax, Cymbalta or another medication that has similar effect? If you were, you might notice that they help relieve the neuropathic pain some as well. One of the good things with methadone is that it is known for helping relieve not only mechanical pain, but neuropathic pain as well.

On going back pain and neuropathic pain, failed back surgery, consult for scs, decided not to do that at this point.
Adhesive Arachnoiditis also......just what I didn't need..9/08- adding bilateral ulnar neuropathy with severe compression to the mix. They want me to see a surgeon for ulnar nerve surgery, but I'm not biting.
I've seen enough surgeons over the last few years.
