Your left leg may go numb sometimes due to a problem with your sciatic nerve.  The sciatic nerve begins in the lower back and runs through the buttock and down the leg.  It is the longest and largest single nerve in the human body.  It is very sensitive and easily becomes irritated.

Sciatic pain comes in a wide range of symptoms and severity.  The most common forms occur in one leg only, start in lower back or buttock and radiate down, and are usually worse when standing or sitting still rather than lying down or walking.  The symptoms you feel (pain, numbness, weakness, tingling) depend on where the pressure on the sciatic nerve occurs.  Most cases are caused by a simple irritation to the nerve and will get better with time and without surgery.

Other possible causes of your left leg going numb include remaining in the same seated or standing position for a long time, pressure on peripheral nerves, lack of blood supply to the leg, various medical conditions, and an abnormal levels of sodium, calcium or potassium in your body.

Your doctor will be able to identify and treat the underlying cause of the numbness in your left leg, so seek professional advice.  Numbness can cause a decrease in feeling so be careful to protect the area from bumps, bruises, cuts and other injuries.

Seek urgent medical attention if weakness or paralysis accompanies the numbness, you can’t control the movement of your leg, or you have muscle spasms, dizziness or other unusual symptoms.

Sounds like a pinched sciatic nerve on the left side in&tbsp;the&tbsp;lower lumbar region of your spine.
The human body has two sciatic nerves, one connected&tbsp;on each side,&tbsp;that run from the lower part of your spine, down the legs and into the feet.
They are the biggest nerves in the body and will cause numbness in the legs and sometimes in the feet if one or both are pinched.
This is usually caused by&tbsp;one or more&tbsp;ruptured discs, which sit in- between&tbsp;the vertebrae of the spine. Standing for long periods of time can aggravate the situation.
If it persists, you may want to think about seeing a neurologist or an orthopedic doctor.
