Pegasus, am sorry you're in such pain, it is a cruel disease.
I have RA, got dx in 1994. By 2000 couldn't work anymore.
In 2004 changed rheumatologist & wanted me to try methotrexate (an older cancer drug).
It has been the best thing yet for me. Knocks the inflammation way down, in fact I go into a remission, so to speak.
Meaning symptoms are tolerable & lab work is good, sed rate might be slightly elevated but doesn't make symptoms any worse. The side effects are minimal.
I have never been on anything narcotic for pain. Not saying I didn't need it or want it, they just don't use narcotics here in States unless someone is severe or post surgery.
This is just my experience, so strictly personal choice.
Wish so much for you to be in less pain.
Take care.
