For osteo-arthritis - a Chinese Medicine specialist told me to avoid dairy of all forms. Helped me tremendously. And you may want to check out Network Spinal Analysis (NSA) - it's a very very GENTLE (super fingertip light touch) to adjust your neck and spine.
There's also a new bodywork called Push Therapy --- it's intense but the results are amazing. I highly recommend all three to manage osteoarthritis.
