I have tried morphine, oxycodone, fentanyl and subutex (same as suboxone) and while the traditional opiates take the edge off (maybe a 20% reduction in pain
with 100 mg morphine and 30 mg
oxycodone) I experienced complete relief from crippled to fine
with 2 mg of subutex. Narcotics are not indicated for RA at all, according to my rheumatologist and everything I see online. They are not very effective either.
