I've had RA for 22 years and it can take a little time to fully develope. Mine got progressively worse over several months, and once it gots worse corticosteriods and DMARDs were my only option. NSAID's are virtually useless in moderate to severe RA. I hope for your sake it doesn't develope further because the side effects of long term use of disease modifying anti rheumatic drugs can be a real pain in the butt.
