Types of Pain and Problems

Brachial or Lumbar Plexopathy

Brachial Plexopathy occurs when the brachial plexus is damaged or placed under pressure. The brachial plexus is a bundle of nerves that come from the spinal cord and supply the arm. The brachial plexus contains several nerves:

  • cervical (neck) roots 4 thru 6
forms the upper trunk
  • cervical root 7
forms the middle trunk
  • cervical root 8 and
forms the lower trunk
  • thoracic (chest) root 1

Brachial Plexopathy may be caused by direct trauma, radiation, tumors, inflammatory conditions, or injury. Symptoms may include pain, numbness, tingling, and/or loss of strength to shoulder, arm, and/or hand. Some patients may experience drooping of the eyes. To diagnose this condition your health care provider will perform specific examinations to test your muscle tone and reflexes. Other diagnostic tests, such as EMG (electromyography)/NCS (Nerve Conduction Study) testing or muscle biopsy may be performed. Treatment includes physical therapy, medication management, or injections. If these treatment options do not work, surgical treatments may be necessary to successfully treat your pain.
