What is Polyneuritis?

Polyneuritis is a condition that results in peripheral nerve inflammation, causing muscle weakness and numbness, among other symptoms. It typically affects many nerves simultaneously and may be associated with autoimmune diseases, neurological disorders, drug problems, infections, metabolic disorders, and physical injuries.


The most common symptoms of polyneuritis include:

  • Numbness and tingling in the limbs
  • Muscle weakness
  • Pain in the arms or legs
  • Loss of coordination and balance
  • Abnormal or uncontrolled movements
  • Difficulty speaking
  • Loss of vision


In order to diagnose polyneuritis, your doctor will perform a physical exam to assess your symptoms. They will also check your reflexes, muscle strength, and sensitivity to light touch. Your doctor may order blood tests, an electromyogram (EMG), or an MRI to rule out other conditions.


Treatment for polyneuritis depends on the underlying cause, but may include medications such as corticosteroids or immunosuppressants, physical therapy, and/or lifestyle changes. In some cases, surgery may be necessary. Treatment may also include occupational therapy and speech therapy to help with communication and other aspects of daily life.


Complications of polyneuritis can include chronic pain, muscle weakness, nerve damage, and decreased quality of life. If left untreated, polyneuritis can also lead to permanent disability.
