Frequently Asked Questions
What are common symptoms of nerve root disorders?

Common symptoms of nerve root disorders include pain, numbness, tingling, and muscle weakness in the affected area. These symptoms often result from conditions such as radiculopathy, where the nerve root is compressed or irritated.

How are plexus disorders diagnosed?

Plexus disorders are diagnosed through a combination of clinical evaluation, imaging studies like MRI or CT scans, and electromyography (EMG) to assess nerve function. These tests help identify the specific location and extent of nerve damage.

What treatment options are available for peripheral nerve disorders?

Treatment options for peripheral nerve disorders include physical therapy, medications such as anti-inflammatory drugs or pain relievers, and in some cases, surgery to relieve nerve compression. Early diagnosis and treatment can improve outcomes and prevent further nerve damage.
