What Are the Risks and Complications of a Nerve Biopsy?

While a nerve biopsy is generally safe, it carries some risks and potential complications, including:

  • Infection: As with any surgical procedure, there is a risk of infection at the biopsy site.
  • Bleeding and Bruising: Minor bleeding and bruising can occur.
  • Nerve Damage: There is a small risk of permanent nerve damage, which can result in chronic pain, numbness, or weakness.
  • Scarring: A small scar may remain at the site of the biopsy.
