Treatment should be started as early as possible. This may prevent the disease from progressing. Treatment usually includes a combination of therapies, such as:

• Medications -- pain medicines, steroids, blood pressure medicines that work on the sympathetic nervous system, bone loss medications (such as Actonel), and antidepressants
• Physical or occupational therapy
• Applications of heat and cold
• The use of a TENS (trancutaneous electrical nerve stimulator) unit
• Biofeedback
• Nerve blocks (injecting medicine to numb the affected nerves or pain fibers around the spinal column)
• Surgical sympathetomy (radical surgery that involves cutting the nerves to destroy the pain, but other sensations may be destroyed as well)

When the disease progresses, the complications include further deterioration of the affected limb, or the spread of the disease to another part of the body.

In addition, there are possible complications associated with some of the nerve and surgical treatments.
