Debi,

I have tried various medications over the 19 years of my PN/SFN and joint pain from Sjogren's. I can tell you that the Fentanyl patch is stronger the BuTrans patch (they are different class/schedule) and you may find it is more helpful. The pharmacist (that is a part of the my pain mgmt clinic) told me that Fentanyl works better on nerve pain than oral oxy & morphine meds...and he was correct. Just thought I would share this, in case you are still considering options. Patches are so much easier to use and you don't have the daily peaks/valleys of pill mgmt (which still come with ER meds).

I wish you luck and hope you get relief soon.
