Symptoms

Symptoms of spinal AVM vary greatly from person to person depending on the severity and location of the AVM. Some people may not develop noticeable symptoms for many years, if at all. Others may experience symptoms that are debilitating or life-threatening.

Symptoms usually develop when people are in their 20s, although almost 20% of people diagnosed with spinal AVM are under the age of 16.

The emergence 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:

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

When to see a doctor
