I feel your pain, so to speak. I also have osteo overlapping with the inflammatory arthritis. According to my rheumy, the inflammatory arthritis can accelerate the osteo beyond what you'd expect for your age. I even have developed severe spinal stenosis in my neck by my mid 50's.
So, I've bounced around various biologics (now Remicade), plus I take Imuran, sulfasalazine, tramadol, Tylenol, and Robaxin. I keep moving as much as I can and rest when fatigued. No perfect answer. I've never had much luck with physical therapy or steroid joint injections.
