What Are the Risks and Complications of a Muscle Biopsy?

Although a muscle biopsy is generally safe, it does carry some risks and potential complications, including:

  • Infection: There is a risk of infection at the biopsy site.
  • Bleeding and Bruising: Some bleeding and bruising may occur around the biopsy area.
  • Pain and Discomfort: Patients may experience pain or discomfort at the biopsy site, which can typically be managed with pain medications.
  • Scarring: An open biopsy may leave a small scar.
  • Nerve Damage: Rarely, the procedure may cause damage to nearby nerves, leading to numbness or weakness.
