A pain that begins in the lower back, radiates out from the buttocks through the back of the thigh and calf, and sometimes down into the feet is the classic sign of lumbar radiculopathy (aka sciatica). Numbness, pain or weakness in different parts of the leg and foot are also commonly reported. Lumbar radiculopathy can be as innocuous as a feeling of pins and needles, but it can also be excruciating and debilitating as well.

Along with the aforementioned lower back pain that travels down the length of the leg, other common symptoms include:

Any of these factors can cause compression or irritation of the lumbar or sacral nerve roots, and result in any of the above pain symptoms.

Diagnosis of lumbar radiculopathy should only be made by an expert physician. In most cases the doctor will be able to diagnose with nothing more than your medical history and a thorough physical examination. He/she will most likely want to know when your symptoms began, their severity, what treatments you have previously tried, and what were the results.

In the physical examination, the doctor will examine the patient for limitations of movement, balance problems, and pain. He/she may also test reflexes in the extremities and evaluate muscle weakness, loss of sensation, and signs of neurological injury.
If needed, an x-ray is obtained to rule out more serious conditions, such as a herniated disc in the lower back, tumor, or other problem.

Lumbar radiculopathy can heal without treatment and surgery is rarely needed. If treatment is prescribed, it is usually a combination of therapy and medication.

Nonoperative Treatments can include:
 Short-term rest
 Cold & Hot Therapy
 Physical Therapy
 Acupuncture
 Massage

Medications for Lumbar Radiculopathy can include:
 Over-the-counter or prescription pain medication
 Anti-inflammatory medication
 Muscle relaxant medication

Interventional Pain Management Treatments
Interventional techniques can be a faster and more definitive method of pain relief for lumbar radiculopathy. These treatments are useful in the presence of severe pain that has failed conservative medical treatment and/or medication.

Lumbar Epidural Steroid Injection – This procedure is considered by many to be the “gold-standard” treatment for lumbar radiculopathy. It is basically the same as a woman will receive during childbirth.  Under fluoroscopic guidance, your physician will place a small needle into the epidural space and inject a small amount of medication to eliminate the pain.
Transforaminal Epidural Steroid Injection – This procedure is similar to the one above; however, in this case the medication is focused directly onto the nerve fibers that make up the sciatic nerve – the result is more medication delivered to the affected area.
Spinal Cord Stimulation (SCS) – When the inflammation in and around the affected nerves is too great for an epidural injection, SCS is an excellent and effective treatment option that can eliminate the pain without surgery. In SCS, an electrical pulse is delivered directly to the spine, blocking certain neuron fibers’ access to the brain and consequently the brain’s ability to sense the previously perceived pain. 
Microdiscectomy – Another option in cases where the  inflammation in and around the affected nerves is too great for an epidural injection.  With microdiscectomy, some of the damaged material around the nerve(s) is removed.

Surgery:
In a minority of cases, the cause of a lumbar radiculopathy may be something that requires surgery to fix. The presence of neurological deficit, cauda equina syndrome (i.e. loss of bowel and/or bladder control), or other problems, may require a surgical intervention.

Prevention Steps:
Part of treatment will be learning healthy spine habits and making lifestyle changes which may reduce current symptoms and prevent further attacks.
