if the arthritis is causing bone spurs to form, I would suggest trying the combination of glucosamine & chondrotin - easy to find in tablet form... but take it a serving of activated yogurt. Bone is naturally made and absorbed by the body, so having the ingredients for repair at hand, so to speak, has helped me deal with normal wear & tear.

That said, be sure that your cartilage & joints are OK... that means a check up with doctor or chiropractor. being out of alignment will aggravate a problem and sometime steroids help prevent further damage to a joint.

Small doses of vinegar can't hurt... maybe use in a salad dressing so you can get your greens as well.
