Clinical Information
  • A syndrome associated with inflammation of the brachial plexus. Clinical features include severe pain in the shoulder region which may be accompanied by muscle weakness and loss of sensation in the upper extremity. This condition may be associated with virus diseases; immunization; surgery; heroin use (see heroin dependence); and other conditions. The term brachial neuralgia generally refers to pain associated with brachial plexus injury. (from Adams et al., Principles of Neurology, 6th ed, pp1355-6)
  • An inflammatory process affecting the brachial plexus. It results in severe pain in the upper extremity and shoulder, upper arm weakness and loss of sensation in the upper arm.
