Have you tried Opana?? I've heard some great stuff on it for pain releif on Opana. I've never tried it myself, but the people I know who take it, swear by it. It comes in a long acting form and a short acting form, so you could take the long acting one daily and the short acting one for breakthrough pain.
Actiq and fentora are great for breakthrough pain, but most insurance will NOT pay for it unless it's being used for cancer pain, and they're VERY expensive!! The fentanyl patches are great also for a choice in pain releif, but like other's have said, it has its downside, like only lasting 2 days instead of 3, ODing if you overheat....
Methadone is also great for pain releif, but that's one you must be very careful with, and must be started low and built up slowly, it has a bad reputation, but when used correctly, it is a great pain releiver, I used it for many years and it worked great.
But the morphine dose your taking does have ALOT of run for being raised, 15mg is the lowest dosage form, at one point I was taking 100mg three times a day, so your nowhere near being out of options for the morphine.
And you said you have taken Norco (hydrocodone 10/325) and had a reaction, but your okay with the 10/660 dose?? Or did I get something wrong there?? Cause I was thinking that maybe you just need to be switched to the 10/325 to help save your liver somewhat.
These are just a few ideas I have, I hope your doctor comes up with something more helpful, building a tolerence to pain medication is part of life when suffering with chronic pain. And thankfully more and more options are being invented all the time lately for pain control.
