I have had the scs implanted.I've been on all kinds of meds including morphine(hated it)until 6 months ago my girlfriend the ER nurse suggested methadone.I talked to my doc and we tried it .In my case it worked well for 3 months and i had to increase the dosage.I take it with Oxycodone but 3 months later Im back to extreme back and leg pain.I just had my scs recalibrated and that is helping but im not sure the morphine is the long term answer.My reply is all over the place because this is my first time. Good luck
