The cells that make up your joints and bones are being replaced every three months. Unless the blood vessels and lymph vessels supplying (nutrients) and draining (metabolic waste and old cells) these areas are congested, they can very well be repaired without the need for smart and expensive medications. These tend to keep the status quo, but don't allow for complete healing. Trying to get every nutrient for your joints is nearly impossible, given the existing congestion.
To heal your blod vessel and lymph system, you need to make some major dietary changes (as described in The Key to Health and Rejuvenation, 1stbooks.com). These include cutting out most protein foods, including meat, fish, eggs, poultry, cheese and milk. To improve digestive functions, you may consider doing liver cleanses (see The Amazing Liver Cleanse, 1stbooks.com). The liver cleanse is a powerful method to restore joint and bone health. The connection between liver and joints is explained in the first chapter of the book.
