Leg Numbness Causes

Having leg numbness can be a symptom of a variety of diseases or medical conditions that have caused injury to the nerves or restricted the blood flow to the nerves. It is a symptom that could be temporary and happens after having prolonged pressure on the nerve or nerves such as riding a bicycle for a long distance or sitting cross legged for a long time. It can also happen with orthopedic conditions that range from moderate to serious and can lead to peripheral nerve or spinal damage. One of these conditions is multiple sclerosis. Leg numbness can also be caused by having a compressed nerve in your lower spine.

Leg numbness due to circulatory problems

These conditions can be caused by a lack of blood flow to the leg because of:

  • Arteriovenous malformation which is a tangled knot of veins and arteries.
  • Buerger’s disease which is an acute clotting and inflammation of your veins and arteries.
  • Deep vein thrombosis which is a blood clot in your leg that could break loose and cause a pulmonary embolism in your lung. It could even cause a stroke or heart attack.
  • Extremely cold temperatures or frostbite.
  • Peripheral artery disease which is a narrowing of your arteries due to the buildup of cholesterol and fat on your artery walls, limiting blood flow to your legs.

Leg numbness due to orthopedic problems

This can happen if there are conditions that damage or injure the nerves because of:

  • Injury to your back
  • Fractures of your bones or having a cast put on that is too tight.
  • Degenerative disk disease.
  • Having a herniated disk.
  • Having nerve pressure or entrapment of the nerve from sitting for a long period of time.
  • Osteoporosis which is a disease where there is destruction of bone tissue and loss of bone mass.

Leg numbness due to neurological problems

This can happen if there is damage or compression of the nerves because of:

  • Injury to your neck or back
  • Alcoholism
  • Diabetic neuropathy which is damage to your nerves because of high blood sugar levels that are associated with diabetes
  • Heavy metal poisoning
  • Hypothyroidism which is having an under-active thyroid gland
  • Multiple sclerosis which is a disease that affects your spinal cord and brain
  • Peripheral neuropathy which is a disorder of your peripheral nerves
  • Having a spinal cord tumor or injury
