as an ayurvedic doctor, i advice not to take painkillers because the analgesis thus achieved does not cure your condition. it actually makes you strain those bones of yours more and thus increases the degeneration. i know most alopaths might disagree.
the cure for arthritis
is there in ayurveda but you will have to do treatment for 4 weeks for three years (depending on your level of degeneration) to cure the condition.
hope i was helpful
