Neurofibroma

Symptoms

The symptoms and signs of a peripheral nerve tumor develop from direct effects on the main nerve or from the tumor pressing on nearby nerves, blood vessels or tissues. As the tumor grows, it may be more likely to cause signs and symptoms, although tumor size doesn't always determine effects.

Signs and symptoms of peripheral nerve tumors vary depending on the location of the tumors and which tissues are affected. They include:

  • Swelling or a lump under your skin
  • Pain, tingling or numbness
  • Weakness or loss of function in the affected area
  • Dizziness or loss of balance

When to see a doctor

See your doctor when you have any of the symptoms listed, especially if you have a lump that grows rapidly.
