Living with Neuralgic amyotrophy

A condition with sudden shoulder and upper arm pain followed by weakness and muscle wasting; there is also an inherited form.

Understanding Neuralgic amyotrophy

Neuralgic amyotrophy, including Parsonage Turner syndrome (PTS), causes sudden shoulder and upper arm pain followed by worsening weakness.

The pain follows the path of one or more nerves and often has no obvious physical cause. It involves the brachial plexus, the network of nerves that controls movement and feeling in the shoulders and arms. PTS is one of two forms. The other is hereditary. GARD lists onset in adulthood.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Upper arm and shoulder pain
  • Arm weakness
  • Muscle wasting in the arm
  • Winged shoulder blade
  • Pins and needles feeling
  • Joint pain

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

    Specialists who may be involved include brain and nervous system specialists.

  3. Ask which tests can help

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

  4. Connect with expert centers

    Autoimmune Association and The Foundation for Peripheral Neuropathy may keep lists of experts for this condition.

  • Connect with Autoimmune Association and other patient organizations
  • Keep notes on symptoms, changes and questions for appointments
  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits

Quick facts

Symptoms usually startAdult
InheritanceAutosomal Dominant

For PTS the cause is still unknown. Suspected triggers include infections, surgery, vaccinations, injury, childbirth, strenuous exercise, and certain medical procedures. The hereditary form is caused by changes in the SEPT9 gene in about 85% of cases.
