Can a Injury in Your Back Cause Numbness and Pain in Your Legs

Do you have lower back or buttock pain that runs down into one thigh or below the knee into the leg? If so, your doctor may diagnose your symptoms as sciatica—a term doctors use to describe compression of the sciatic nerve. Sensations, or unusual feelings may include numbness, tingling, pins and needles, and sometimes pain is described as electric-shock-like. Depending upon the individual nerve that is affected, pain can radiate only into the buttocks or all the way down to the foot. A common cause of sciatica and nerve compression is a lumbar disc herniation or bone spur that presses on a spinal nerve in the low back.

Sciatica pain radiates along the sciatic nerve, usually from the low back, down the buttocks, into the thigh and leg. One hallmark of classic sciatica is the pain and symptoms are felt below the knee and sometimes into the foot and great toe. Usually, sciatica only affects one side of the lower body.

Radicular Pain, Radiculopathy

Radicular pain or radiculopathy are other terms your doctor may use when discussing sciatica. A radiculopathy is pain and/or adverse sensation that travel along a nerve. When a spinal nerve root is compressed, pinched or injured, it may become inflamed. Lumbar (low back) conditions that may cause this type of problem are spinal stenosis, foraminal stenosis or herniated disc.

Proper Diagnosis Essential to Treatment

The doctor will ask you about your symptoms, such as:

• When the pain started
• Where you feel the pain
• Activities that reduce or worsen pain and symptoms
• Whether the pain goes all the way down your leg or stops at the knee
• Is there weakness or tingling in your legs and/or feet?
• How severe your pain is, on a scale of 1 to 10 (10 is the worse pain imaginable)

The doctor may perform a straight-leg test to see if you have an inflamed nerve. You lie on your back while the doctor lifts each leg. If lifting a leg causes, or produces sciatic-like pain and sensations, you may have a bulging or ruptured disc.

The doctor may ask you to walk as you normally do, then on your heels and next, your toes. This helps the doctor to check your balance and aspects of lower-body strength. Compression of the nerve can cause muscle weakness in the foot which will be revealed by these tests.

During your exam, your doctor will:

• Look at your posture and range of motion
• Note any movement that causes pain
• Examine the curvature and alignment of your spine
• Feel for muscle spasm
• Check your sensation
• Test your reflexes and muscle strength

Your doctor may order a plain x-ray, CT scan or MRI. The CT scan or MRI provides the doctor with many snapshots of your spine, and can help confirm a suspected diagnosis. The findings of an imaging test are compared to the information the doctor gathers during the taking of your medical history, and physical and neurological examination results. An accurate diagnosis is one of the first steps in determining the best treatment options.

What Else Could it Be?

Only your doctor can tell for sure if your symptoms are sciatica. There are many other structures in the spine that can cause similar types of pain. For instance, the joint between the pelvic and sacrum (sacroiliac joint, or SI joint), the lowest part of the spine can cause pain in the buttock. You may also feel sciatica-like pain if you sprain a low back facet joint, which are the connecting joints in the back part of the spine. A tear in a disc can cause pain down into the leg. The hip joint can occasionally cause pain in the thigh.

Sciatica Treatment

Sciatica usually can be treated non-surgically with brief (24 to 48 hours) bed rest and pain relievers such as ibuprofen or acetaminophen. In some cases, the doctor may prescribe medication that relieves nerve pain, such as gabapentin. Oral steroids are a good medication to calm down nerve pain. In most cases, patients with sciatica feel better over time, usually within a few weeks. If pain persists, injections might be discussed.

Muscle spasms, which may accompany sciatic symptoms, may be treated with heat or cold. Your doctor may tell you to take short walks, and may prescribe physical therapy. Once you recover, your doctor may give you exercises to strengthen your back.
