Osteoarthritis (OA) of the Spine:
This is a condition of the discs between vertebrae with loss of cushioning, fragmentation and herniation related to aging. There may be no symptoms; but in some cases, the spine loses flexibility and bone spurs may pinch a nerve root, causing pain or weakness.
Osteoarthritis (OA) of the Knee:
When the protective tissue (cartilage) in the knee joint wears down, it leaves the ends of bone bare and unprotected, causing bone spurs and pain.
Osteoarthritis (OA) of the Hip:
Another common joint that may lose cartilage from the joint disease (osteoarthritis) and thereby feel the pain of bone spurs and pinched nerves.
Ozone therapy has proven to be an effective treatment for those diagnosed with degenerative disc disease.
