Sciatica symptom relief has been hard to come by for many sciatica sufferers, but a new treatment option is now available that brings fast relief with a minimal risk of side effects to the vast majority of sciatica sufferers.

Sciatica (commonly misspelled as syatica) is an irritation of the sciatic nerve which is formed by nerves that arise in the low back. Most cases of sciatica are caused by herniations or bulges of one or more spinal discs. The spinal discs are soft tissue structures that separate the spinal bones (the vertebrae) and act as shock absorbers.

When a spinal disc is damaged through a single injury or multiple small injuries over time, the outer wall of the disc may not be able to contain the pressure from within and the disc bulges outward into the canals where the spinal nerves exit the spine. This results in compression and irritation of the nerves, which often produces sciatica that begins in the buttock muscles and may travel downward across the back of the leg to the bottom of the foot.

The treatment options for sciatica symptom relief vary depending on the case. The first line of sciatica treatment is usually medication to reduce pain and inflammation. Muscle relaxers may also be prescribed to reduce muscle spasm. Medication may be effective enough to provide relief short-term until inflammation subsides and/or the disc stabilizes. In more severe cases, oral medication may not be effective, and some patients may not be able to tolerate the common side effects of anti-inflammatory drugs and/or the diminished mental alertness seen with pain killers and muscle relaxers.

Steroid injections are often the next line of sciatica symptom relief treatment, and they are used to try to reduce inflammation around the discs and spinal nerves. While steroid injections often provide relief short-term, the long-term effects are less favorable. Due to the fact that the main effect of steroid injections is to reduce inflammation, once those effects wear off, inflammation and the resulting pressure on the nerves often builds up again, and symptoms return. Steroid shots come with a number of side-effects including bone thinning, damage to soft tissues, and suppression of immune function, so doctors limit the amount of steroids used in order to avoid adverse health effects from the treatment.

Surgical treatment is often suggested for sciatica sufferers, and in a few cases it may be the only real option. Surgery has a poor track record (about a 50% success rate overall), and in some cases, symptoms may worsen following surgery. Complications of surgery include problems from post-surgical scar tissue formation and increased stress on adjacent spinal discs which may result in additional problems with other discs in the years following surgery.

Fortunately, there is a new option in sciatica symptom relief that has a high success rate and a very low risk of side-effects. Spinal decompression is a new, advanced form of spinal traction that uses special computerized traction motors to gently and slowly apply a decompressive force to the spine, reducing pressure in the spinal discs. Spinal decompression systems can comfortably create negative pressure (suction) within the spinal discs that can pull disc bulges and herniations back in and away from sensitive nerve structures, as well as increase disc hydration and nutrition to help with disc healing. Unlike the old forms of spinal traction which could be painful due to the traction pull triggering muscle spasm, spinal decompression systems monitor and respond to the body to keep muscles relaxed so the treatment is comfortable and effective.

Preliminary studies have shown a success rate for spinal decompression of 80 to 90%, with the beneficial effects holding up well over the long-term. The one-year recurrence rate post-treatment is less than 5%. While spinal decompression is not appropriate for everyone with sciatica and is not effective in every case, it does represent a big improvement in sciatica treatment.

Sciatica exercises are an important part of both short and long-term treatment, but it is critical to choose the right exercises. Even commonly-recommended exercises for sciatica may not be indicated during times of severe acute symptoms, and some exercises may only make things worse.

For example, while commonly recommended to people with sciatica, exercises such as hamstring stretches and the yoga position, “downward facing dog” can be beneficial as part of managing one’s condition once the pain is reduced, these exercises can place tension on the sciatic nerve and aggravate an already inflamed and sensitive condition. In general, any exercise that causes pain to increase in the leg and/or extend further down the leg should be completely avoided during the acute phase of sciatica.

During the acute phase of sciatica pain, McKenzie exercises provide one of the best and safest treatment approaches available – more effective than medication and epidural steroid injections in many people. Though often associated with spinal extension and mistakenly called the “McKenzie Extension Exercises”, McKenzie method may involve any number of spinal positions/movements. The whole point of the McKenzie method is to evaluate different positions/exercises to find what best produces “centralization” of symptoms.

McKenzie practitioners use the word “centralization” when the pain and other symptoms are relieved in the areas the greates distance away from the spine. To give an example, in a person with sciatica all the way down the leg to the foot, centralization might occur in which the pain left the foot and lower leg and then only extended down to the knee. Or, if sciatica symptoms started out going as far as the knee, centralization would be if the symptoms left the thigh and only went as far as the hip area.

A position or exercise that results in symptom centralization is one that will be beneficial, even in situations where symptoms increase for a time in areas closer to the spine. For example, if you had sciatica and low back pain and tried one of of the McKenzie exercises and the sciatica completely went away but the back pain got worse, the exercise would still be considered beneficial and it would be recommended to continue using it. In the long run, a sciatica exercise that produces centralization will usually eventually result in improvement in all symptoms, even if more central (closer to the spine) symptoms get worse at first.

The simplest of the McKenzie exercises for alleviating sciatica is done by simply lying on one’s stomach on the floor or a firm surface and propping one’s chest up on the elbows. This places the lower spine in a gentle extension, which can help relieve sciatica by pushing bulging spinal discs forward, and away from the nerve roots that form the sciatic nerve, reducing pressure and irritation. Although you can maintain this position for relatively long periods of time, I recommend doing it for short periods of one or two minutes with a rest break of at least a few minutes in between. The frequent breaks prevent the low back muscles from tightening up as much, and yet still allows for good overall results. For more complex sciatica exercises, getting detailed instructions either through an illustrated guide or an experienced health care practitioner is advised.
