What is Sciatica?
Sciatica is a symptom of a problem with the sciatic nerve, a large nerve that runs from the lower back down the back of each leg. It controls muscles in the back of your knee and lower leg and provides feeling to the back of your thigh, part of your lower leg and the sole of your foot. When you have sciatica, you have pain, weakness, numbness or tingling. It can start in the lower back and extend down your leg to your calf, foot, or even your toes. It's usually on only one side of your body.It is caused by injury to or compression of the sciatic nerve. Sciatica is a symptom of another medical problem, not a medical condition on its own.
What are the symptoms of Sciatica?
Sciatica pain can vary widely. It may feel like a mild tingling, dull ache, or a burning sensation. In some cases, the pain is severe enough to make a person unable to move.
The pain most often occurs on one side. Some people have sharp pain in one part of the leg or hip and numbness in other parts. The sensations may also be felt on the back of the calf or on the sole of the foot. The affected leg may feel weak.
The pain often starts slowly. Sciatica pain may get worse:
- After standing or sitting
- At night
- When sneezing, coughing, or laughing
- When bending backwards or walking more than a few yards, especially if caused by spinal stenosis
What are the causes of Sciatica?
Sciatica occurs when there is pressure or damage to the sciatic nerve. This nerve starts in the spine and runs down the back of each leg. This nerve controls the muscles of the back of the knee and lower leg and provides sensation to the back of the thigh, part of the lower leg, and the sole of the foot.
Common causes of sciatica include:
- Piriformis syndrome (a pain disorder involving the narrow piriformis muscle in the buttocks)
- Slipped disk
- Degenerative disk disease
- Spinal stenosis
- Pelvic injury or fracture
- Tumors
Who is at risk for Sciatica?
Risk factors for Sciatica include:
- Diabetes
- Inactivity and sedentary lifestyles
- Increasing Age
- Manual Labor that requires strenuous use of your back and/or heavy lifting
How to know you have Sciatica?
Sciatica might be revealed by a neuromuscular examination of the legs by a physician. There may be weakness of knee bending or foot movement, or difficulty bending the foot inward or down. Reflexes may be abnormal, with weak or absent ankle-jerk reflex. Pain down the leg can be reproduced by lifting the leg straight up off the examining table.
Tests are guided by the suspected cause of the dysfunction, as suggested by the history, symptoms, and pattern of symptom development. They may include various blood tests, x-rays, MRIs, or other tests and procedures.
When to seek urgent medical care
Call your doctor right away if you have:
- Unexplained fever with back pain
- Back pain after a severe blow or fall
- Redness or swelling on the back or spine
- Pain traveling down your legs below the knee
- Weakness or numbness in your buttocks, thigh, leg, or pelvis
- Burning with urination or blood in your urine
- Pain that is worse when you lie down, or awakens you at night
- Severe pain and you cannot get comfortable
- Loss of control of urine or stool (incontinence)
Also call if:
- You have been losing weight unintentionally
- You use steroids or intravenous drugs
- You have had back pain before but this episode is different and feels worse
- This episode of back pain has lasted longer than 4 weeks
If any of these symptoms are present, your doctor will carefully check for any sign of infection (such as meningitis, abscess, or urinary tract infection), ruptured disk, spinal stenosis, hernia, cancer, kidney stone, twisted testicle, or other serious problem.
Treatment options
Because sciatica is a symptom of another medical condition, the underlying cause should be identified and treated.
In some cases, no treatment is required and recovery occurs on its own.
Conservative treatment is best in many cases. Your doctor may recommend the following steps to calm your symptoms and reduce inflammation.
- Apply heat or ice to the painful area. Try ice for the first 48 - 72 hours, then use heat after that.
- Take over-the-counter pain relievers such as ibuprofen (Advil, Motrin IB) or acetaminophen (Tylenol).
- While sleeping, try lying in a curled-up, fetal position with a pillow between your legs. If you usually sleep on your back, place a pillow or rolled towel under your knees to relieve pressure.
If at-home measures do not help, your doctor may recommend injections to reduce inflammation around the nerve. Other medicines may be prescribed to help reduce the stabbing pains associated with sciatica.
Physical therapy exercises may also be recommended. Additional treatments depend on the condition that is causing the sciatica.
Nerve pain is very difficult to treat. If you have ongoing problems with pain, you may want to see a neurologist or a pain specialist to ensure that you have access to the widest range of treatment options.
Invasive therapies
Minimally invasive procedures
Intradiscal Electrothermoplasty (IDET)
A needle is inserted into the affected disc, guided by x-ray. A wire is then threaded down through the needle and into the disc until it lies along the inner wall of the annulus. The wire is then heated which destroys the small nerve fibers that have grown into the cracks and have invaded the degenerating disc. The heat also partially melts the annulus, which triggers the body to generate new reinforcing proteins in the fibers of the annulus.
Radiofrequency Discal Nucleoplasty (Coblation Nucleoplasty)
A needle is inserted into the affected disc, although instead of a heating wire, a special RF probe (radio frequency) is used. This probe generates a highly focused plasma field with enough energy to break up the molecular bonds of the gel in the nucleus, essentially vaporizing some of the nucleus. The result is that 10-20% of the nucleus is removed which decompresses the disc and reduces the pressure both on the disc and the surrounding nerve roots. This technique may be more beneficial for sciatica type of pain than the IDET, since nucleoplasty can actually reduce the disc bulge, which is pressing on a nerve root. The high-energy plasma field is actually generated at relatively low temperatures, so danger to surrounding tissues is minimized.[1]
Alternative therapies
The approach to treating Sciatica is to reduce the compressive forces causing the pressure upon the sciatic nerve. This can be accomplished through traction and realignment therapeutic procedures in the case where the sciatica is spinal-related.
- Acupuncture
- Chiropractic manipulation for the restoration of normal joint biomechanics and reduction of histochemical irritation to the involved nerves. [2][3][4]
- Massage therapy to the involved lumbopelvic muscles.
- Structural Integration A systematic approach designed to reorganize major joints, and body segments (such as the lower back region and sacrum), while releasing the chronically held tension and torsion patterns. The goal is to achieve a rapid change in structural mechanics and correction of chronic musculoskeletal pain or dysfunction.
Where to find medical care for Sciatica
Directions to Hospitals Treating Sciatica
Prevention of Sciatica
Prevention varies depending on the cause of the nerve damage. Avoid prolonged sitting or lying with pressure on the buttocks.
What to expect (Outlook/Prognosis)
If the cause of the sciatic nerve dysfunction can be identified and successfully treated, full recovery is possible. The extent of disability varies from no disability to partial or complete loss of movement or sensation. Nerve pain may be severe and persist for a prolonged period of time.
Possible Complications
- Partial or complete loss of leg movement
- Partial or complete loss of sensation in the leg
- Recurrent or unnoticed injury to the leg
- Side effects of medications
