Symptoms of Spinal Schwannomas

As the tumor grows, it will affect different parts of the spine, nerves, blood vessels and bones. As the this growth occurs, symptoms will vary, including:

  • Back pain
  • Weakness or numbness in the arms and legs
  • Electric-like shock sensations when the affected area is touched
  • Loss of bladder or bowel function
  • Paralysis


Because these symptoms can appear with or like other conditions, it is important to be seen by a doctor for proper diagnosis and treatment. If left untreated, even non-cancerous tumors can grow and cause severe nerve and spine damage, and sometimes paralysis. (See Diagnosing and Treating Spinal Schwannomas.)
