What is sciatica (sciatic nerve pain?)
Sciatica is:
- one of the most common health complaints of the lower back and leg,
- one of the most common kinds of nerve pain in the body,
- and it can be one of the most difficult conditions to resolve without proper chiropractic care.
Sciatica is nerve pain that follows the path of your sciatic nerve. Its technical definition is “inflammation of the sciatic.”
The sciatic nerve is the nerve that supplies nervous system energy to the muscles and skin of the lower leg.
With this kind of nerve pain, you may feel the pain anywhere along the path of the sciatic nerve. You may have pain in the lower back, buttocks, lower leg and/or foot.
You do have a sciatic nerve on both the right and left side of the body. But sciatica usually occurs on only one side at one time.
The hardest thing to understand about sciatica
This is perhaps the hardest thing to understand about sciatica symptoms.
Sciatica itself is not a medical condition–it describes a set of symptoms that are caused by another health condition. So sciatica is never a cause of anything. It is just the result of something.
Any condition that puts extra pressure on the sciatic nerve or the roots of the sciatic nerve can cause the symptoms of sciatica. And this is why it’s so tricky.
For example, a bulging disc or a extremely tight piriformis muscle (a muscle of the buttocks) can both cause sciatica.
Where is the sciatic nerve?
The sciatic nerve is the largest nerve in your body. The sciatic nerve emerges from the spinal cord in the lower back. It travels through the pelvis and then runs through thigh muscles on the back of the leg.
Around the back of your knee it splits into two—and one half travels down the back of the leg into the foot. The others travel down the front and side of the leg into the foot.
The sciatic nerve supplies sensation (feeling) to the skin of most of the lower leg and the foot.
It also controls your leg and foot muscles. If you pick up your leg and look at your toes right now, you are using your sciatic nerve to do that.
What are the the most common sciatica symptoms?
These symptoms usually occur on one side of your body. Do you have any of these sciatica symptoms?
- Buttock pain
- Low back pain
- Calf pain
- Numbness (in skin of leg and/or foot)
- Pain in one part of leg, numbness in another
- Tingling, or pins and needles sensations (also called parasthesias)
- Muscle weakness
- Loss of muscle control
- Loss of bladder or bowel control (rare–requires immediate medical attention)
Sciatica nerve pain may feel like:
- Mild ache
- Dull ache
- Sharp, burning sensation
- Intense pain
- Jolt or electric shock
- Shooting pain that travels down the path of the sciatic nerve
Sciatica can be aggravated by or made worse by the following situations:
- Lying in bed at night
- Sneezing, coughing or laughing
- Bending backward or walking
- Standing or sitting for prolonged periods of time
What causes sciatica?
All sciatica pain is caused by anything that puts extra pressure on the sciatic nerve (somewhere in the buttocks or leg) or the sciatic nerve roots, up in the spine.
According to some experts the most common cause of this type of pressure is a ruptured/herniated disc in lower back.
(The disc is a pad of cartilage between your spinal bones. When it breaks down it can dry out and start to bulge near your spinal cord. However, disc bulges are relatively common. And not everyone who has a bulging disc gets sciatica pain.)
Some experts say that about 90% of cases of sciatica are caused by spinal disc herniation. Either the herniated disc itself or the swelling associated with it can lead to compression of the sciatic nerve.
There are other less common, but potential causes of your sciatica including:
- Spinal stenosis (a narrowing of the spinal canal that puts pressure on the spinal cord, for example bone spurs are one cause of spinal stenosis)
- Piriformis syndrome In some people the sciatic nerve runs through or under this muscle, so that muscle spasm, trauma or overuse puts pressure on the sciatic nerve
- Pregnancy (additional weight of the fetus can put extra pressure on sciatic nerve)
- Pelvic injury or fracture
- Tumors
In some cases of sciatica symptoms, there is no identifiable underlying cause. When the doctor orders an MRI, the disc isn’t bulging (no spinal disc herniation). There is no obvious piriformis syndrome. There is no spinal stenosis.
In these situations, your doctor may have a hard time explaining why you have sciatica. In that case it might be hard to find sciatic nerve pain relief if you don’t respond to typical medications.
