Living with Amyotrophic neuralgia

A hereditary nerve condition with episodes of severe pain and muscle loss in the shoulders and arms.

Understanding Amyotrophic neuralgia

Amyotrophic neuralgia, also called hereditary neuralgic amyotrophy, is a nervous system disease that affects the brachial plexus, the nerves that control the arms and shoulders.

Episodes of severe pain and muscle loss can occur in one or both shoulders and arms and last from a few hours to a few weeks. Over time, there can be decreased or odd sensations, long-term pain, and trouble moving. Attacks may happen by chance or be triggered by exercise, childbirth, surgery, or infection. People in some families share distinct physical and facial features.

Signs & symptoms

GARD doesn't list a separate symptom list for this condition. The summary says symptoms may include:

  • Severe pain in the shoulders and arms
  • Muscle loss in the shoulders and arms
  • Numbness and tingling
  • Long-term pain
  • Trouble moving the arms

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Hereditary Neuropathy Foundation Inc. may keep lists of experts for this condition.

Quick facts

InheritanceAutosomal Dominant

Changes in the SEPT9 gene can cause this condition. It is inherited in an autosomal dominant way, so a changed copy of the gene from one parent can be enough.
