Massage to decrease pain

Chronic Pain
Chronic pain can have many causes which may include: Sudden Trauma to musculoskeletal tissues (muscles, ligaments, tendons, and bursa). Repetitive motions, lack of activity, nervous tension or stress. Surgery to correct a problem may also cause chronic pain by creating scar tissue. Scar tissue from surgery extends the full thickness of skin, and myofascia this in turn pulls on all of the overlying and underlying structures.
When there is an injury to a bone muscles will contract to help splint the injury to help prevent further injury to the surrounding tissues. After the bone heals the muscles, tendons and ligaments will be shortened. Without intervention this can create contractures and loss of flexibility and mobility.
Chronic pain is one of the leading causes of disability. It touches every part of a person's life impacting family, and the socioeconomic status. Chronic pain is difficult to treat it has developed sometimes over many years. It can take many treatments to release the adhesions, scar tissue and restore normal skeletal alignment.

Structural Changes
The constant force exerted by the muscles, tendons, and ligaments will create structural changes at the attachment points. The cartilage, disks, and bursa are damaged by the exerted forces over an extended period of time.
The disks between vertebrae will be compressed; bulge then will rupture after prolonged pressure on it.
The cartilage at the ends of bones will be eroded by the constant pressure.
Articulating joints work with the support of muscles, tendons and ligaments. When these become tight
or when they become unbalanced and pull at an angle and will begin to
damage the joint and capsule.
Rebalancing muscles around joints and other articulating structures help keep the pressure equalized and help prevent injuries.
