Sciatica encompasses symptoms of pain that are caused by irritation or compression of one or more nerves exiting the lower spine. The sciatic nerve is comprised of a long pathway of nerves branching off to reach from the spine to the feet. Radiculopathy (the appropriate medical term for sciatica) simply means the spinal disc has expanded and is irritating the nerve root (radicular nerve) connecting to the sciatic nerve.

While the most common cause for sciatica is a herniated disc from some type of injury, there are other causes which must be considered for proper diagnosis and treatment. For instance, osteoarthritis may cause irregular projections of bone that put pressure on the sciatic nerve space, or a sprained ligament may be causing swelling in the lower back. Rare sciatica causes include Paget's disease, spinal stenosis, a blood clot, tumor, or diabetic neuropathy.

As you can see from the variety of possible sciatica causes, it's important to know the origin so that proper treatment can be initiated. Generally, sciatica can be resolved by identifying and treating the underlying cause. An MRI, CT scan, or nerve function test may be necessary in order to determine the specific cause of your sciatica.
