Most people with spinal AVM experience few if any significant symptoms.

When symptoms do occur, they vary depending on the severity and location of the AVM. These symptoms usually appear when people are in their 20s, although almost 20 percent of people diagnosed with spinal AVM are under the age of 16.

The onset of symptoms may be sudden or gradual. Symptoms typically include:

  • Problems with walking or climbing stairs
  • Numbness, tingling or sudden pain in your legs
  • Weakness on one or both sides of your body

As the condition progresses, additional symptoms may include:

  • Lack of feeling in the legs
  • Difficulty urinating or moving your bowels
  • Lower back pain
  • Headache
  • Stiff neck
  • Sensitivity to light

When to see a doctor

Make an appointment with your doctor if you experience signs and symptoms of spinal arteriovenous malformation.
