Dave has taken anti-inflammatory and pain medications for 3 years to combat the pain in the larger bones in his body, specifically in his hips, shoulders and spine.

The cause of this disease is unknown, and often results in the joining together (ankylosis) or 'freezing' of the bones of the spinal column.

In advanced stages, surgery is performed in an attempt to alleviate the pain. The ankylosis is due to destruction of cartilage and bone, similar to the destruction in rheumatoid arthritis.

Dave also has arthritis in other areas of his body, including his hands.

After 9 sessions, Dave was able to stop taking all pain medication and anti-inflammatory drugs.
