These symptoms can appear when you switch from one strong opiate to another.Methadone would render the
oxycodone useless especially after you go above 80 mgs a day of
methadone.So I don't understand the doctor ordering that in the first place as it would do absolutely nothing for your pain.
Methadone alone is probably your best bet although
Opana ER is also an exellent pain killer for chronic pain.
If it's been more then 2 weeks since you changed over then I would definately get after your doctor.
Give the Opan ER a chance as it is a powerful pain killer and useually does the trick......Good luck..Let us know how you make out.......Dave
