Signs and Symptoms of Peripheral Nerve Tumors

The most common symptom of a peripheral nerve tumor is pain (at rest or sometimes when pressure is applied to the area, such as when sitting). It can also cause neurologic symptoms like numbness, tingling, or weakness. These tumors may also first be noticed as a lump or swelling under the skin. They tend to grow slowly and are for the most part benign. Signs and symptoms vary depending upon the location of the specific peripheral nerve involved, as well as its size, and any nearby structures that are compressed, such as blood vessels or internal organs.

The following symptoms can be caused by peripheral nerve tumors:

  • Numbness
  • Pain
  • Swelling, lumps, or bumps on or under the skin
  • Tingling
  • Visible mass
  • Weakness in the affected area
