Anatomy & Background
The vertebra of the lumbar spine are the largest vertebra in the body because they carry the most weight and are subject to the greatest amount of stress, and is also most associated with back and leg pain.
The two lowest levels (L4-L5) and (L5-S1) have the most flexion and extension motion stress, and the highest rate of injury. The intervertebral discs of these two levels also have the highest rate of disc degeneration and herniation. The L5 vertebra is the most common site of spondylosis and spondylolisthesis. The most common lumbar nerves that get pinched or entrapped are the L4, L5, S1 levels. Entrapment of these nerves may lead to a condition called Sciatica.
The spinal nerves are the electrical wires of the body. They originate at the spinal cord and exit the spinal column through the intervetebral foramen. Nerves exiting the area of the lumbar spine provide sensation and motor control to the back, buttocks, legs and down to the foot. Damage or interference with the transfer of information of these nerves can cause neurological problems such as pain, weakness, abnormal sensations, numbness and changes in spinal reflexes. These symptoms may occur in the back, leg and down to the foot.
What is Sciatica?
Sciatica is a common nerve irritation. The sciatic nerve can produce pain, numbness, and weakness down the leg along the areas innervated by the sciatic nerve. It is located under the piriformis muscle.
According to PubMed, inflammation and compression are essential for the symptomatic nerve root. Studies indicate that people with physically demanding jobs run a higher risk of sciatica compared to the general population. It’s advised to stay active and use prescribed non-steroidal anti-inflammatory drugs. Epidural corticosteroid injections and transforaminal peri-radicular injections of corticosteroid can treat your knee pain. Sciatica surgery may be an option if you don’t have severe progressive neurological symptoms.
What Are the Causes of Sciatica?
Anything that encroaches on or puts pressure on the sciatic nerve can be considered a cause of sciatica. Leading specialists suggest that the common sciatica causes include:
- Herniated discs that place pressure on the nerve, in addition to inflammation that irritates the nerve.
- Degenerative joint disease resulting in the formation of bony spurs on the facet joints can narrow the intervertebral space placing pressure on the exiting nerve.
- Trauma or muscle spasms can put pressure on the peripheral nerve, producing symptoms along that nerve’s distribution.
- Degenerative disc disease that results in wear on the intervertebral disc, and a reduction in disc height may result in loss of space at the intervertebral foramen compressing on the exiting nerve.
- Tightness of the piriformis muscle resulting in compression on the sciatic nerve underlying the muscle.
What Are the Symptoms of Sciatica?
Sciatica symptoms will be located along the path the sciatic nerve travels. The most common signs are listed below:
- Pain in the back or radicular to the buttock, into the leg and extending down behind the knee, to the foot depending on the nerve involved and the severity of the encroachment.
- Pain and tenderness localized at the level of the involved nerve.
- Muscle spasm and changes in posture in response to the injury.
- Pain with excess activity and relief with rest.
- Pain and tenderness localized at the level of the involved nerve.
- Loss of motion like the inability to bend backward, move sideways to the effected side, or stand erect for extended periods of time.
- Sitting, standing and walking can be difficult if the irritation is severe.
- Impairment of normal reflexes in the lower extremity.
- Numbness tingling may be experienced from the low back to the foot depending on the distribution of the affected nerve.
- Muscle weakness may occur on any muscle that is innervated by the pinched nerve. Long-term pressure on the nerve can produce atrophy or wasting of that particular muscle.
If you experience any of the aforementioned signs of sciatica, you should not wait any longer and seek medical assistance promptly.
How Is the Condition Diagnosed?
Sciatica diagnosis begins with a review of your full medical history. It includes an examination of the following factors:
- The locations of your pain
- Pain level
- Whether you have had any recent injuries
Your doctor will also need to know what makes the condition better and what makes it worse, as well as when and hot it started.
The next step is the physical examination. It involves testing your muscle strength and reflexes. Your healthcare provider can also ask you to perform some moving exercises and sciatica stretches. These exercises will help determine the activities that cause more pain. To determine the root cause of the problem, your doctor also performed imaging tests and the most common ones used to come up with a diagnosis are:
- CT scans
- Spinal X-rays (regular X-rays are not able to provide a complete view of sciatic nerve damage)
Your healthcare provider can also order a CT myelogram. To perform this test, a doctor will inject a special dye into your spine to help create clearer pictures of your nerves and spinal cord.
Sciatica pain treatment will depend on the severity of the condition, and the underlying cause of the nerve damage.
When treating acute back problems, you can make use of the following recommendations:
- Rest. Avoid the activities that produce the pain (bending, lifting, twisting, turning, bending backward, etc).
- Anti-inflammatory drugs and other sciatic nerve pain medications.
- Apply ice in acute cases to the lumbar spine to help reduce pain and associated muscle spasm. Apply ice right away and then at intervals for about 20 minutes at a time. Do not apply directly to the skin.
- An exercise regiment designed specifically to address the cause of the symptoms associated with sciatica and improve joint mobility, spinal alignment, posture, and range of motion.
- Steroidal medication to reduce inflammation in moderate to severe conditions.
- Lumbar nerve or epidural injections
- Physical therapy for back and disc problems must remain conservative at the beginning to avoid aggravating the condition. Your therapist should emphasize rest, reducing the inflammation, and increasing the blood circulation for healing. Once the initial inflammation has been reduced, a program of stretching and strengthening should be initiated to restore flexibility to the joints and muscles involved, while improving the strength and stability of the spine. Each program will be based on the structure causing the problem and symptoms. A program not tailored to the specific problem may aggravate symptoms
Our doctors offer the most advanced and the best treatment for sciatica pain.
In mild cases patients found that rest, ice and medication were enough to reduce the pain. Specialists at Redefine Healthcare recommended physical therapy to develop a series of postural, sciatic nerve stretches and strengthening exercises to prevent reoccurrence of the injury. Return to activity should be gradual to prevent a return of symptoms.
Moderate to Severe Cases
If the problem persists, consult with your local pain management health care provider or our best rated sciatica treatment doctors and specialists of Redefine Healthcare in New Jersey. Our physician will perform a thorough evaluation to determine the possible cause of your symptoms, the structures involved, the severity of the condition, and the best course of sciatica treatment.
In addition to performing a thorough examination your local sciatica treatment doctor or experienced pain management doctors in New Jersey of Redefine Healthcare may order the following tests to make a more concise diagnosis:
- X-ray to determine if there is any joint degeneration, fractures, bony malformations, arthritis, tumors or infection present.
- MRI to determine any soft tissue involvement, including visualization of the discs, spinal cord and nerve roots.
- CT scans, which can give a cross section view of the spinal structures.
Medications to consider
Our pain relief doctors and sciatica treatment specialists of pain management clinics of New Jersey may recommend several medication options individually or in combination to reduce the pain, inflammation and muscle spasms that may be associated with sciatic nerve irritation.
- Over the counter medications for mild to moderate pain.
- If over the counter medications are not effective your physician may prescribe stronger pain medication.
- Anti-inflammatory drugs or prescription NSAIDS (non-steroidal anti-inflammatory drugs) to reduce inflammation following acute injury.
- Muscle relaxers to reduce acute muscle spasm.
- Injections like facet injections, nerve blocks or an epidural. These may involve the injection of corticosteroids to a specific structure to reduce local inflammation.
Severe or Non-responsive Conditions
In the case of conditions that do not respond to conservative care surgery may be indicated. If you continue to experience some of the following symptoms:
- Increase in radiating or radicular pain
- Pain or nerve irritation that gets worse
- Weakness with muscle atrophy
- Associated disc involvement
If symptoms continue to get worse, talk to our doctor, a surgery may be indicated to release entrapment and remove the degenerative changes that are compromising the nerve.
Injections like facet injections, nerve blocks or an epidural. These may involve the injection of corticosteroids to a specific structure to reduce local inflammation caused that is irritating the nerve roots of the Sciatic Nerve.
