Causes of sciatica are varied, and unfortunately in many cases the cause of sciatic pain cannot be identified. It is believed that the general wear and tear of the body can result in sciatica pain, which can usually be relieved with some form of sciatica treatment. Sciatica is caused by injury to, or compression of the sciatic nerve.

Causes of Sciatica

Sciatic nerve pain starts when the main nerve into your leg, the sciatic nerve, is irritated, pinched, or compressed in some way. This can happen for one or more of several reasons; the following are the main causes of sciatica:

• Isthmic Spondylolisthesis – A stress fracture in the fifth lumbar vertebra, known as L5 can cause disc movement and hence sciatic symptoms.
• Piriformis Syndrome – The Piriformis muscle is located in your lower back and can sometimes spasm, resulting in sciatica symptoms.



• Degenerative Disc Disease – The discs in your spine will age just as you do and are prone to wear and tear like the rest of your body. Your discs are aging and one of them has given way, hence pinching, irritating or putting pressure on your sciatic nerve.
• Lumbar spinal stenosis – Different roots of the sciatic nerve pass through passageways in the spine. The passageways could become smaller, which will result in pinching, irritation or increased pressure on the nerve.
• Lumbar herniated disc – The discs in your spine are like shock absorbers, allowing your back to bend and swivel. The effects of ageing may weaken or damage the discs and a disc can bulge out, split, cause pinching or putting pressure on your sciatic nerve. This is one of the most common causes of sciatica pain.
• Trauma – Accidents that causes sudden compression of the sciatic nerve can produce great pain, for example, breaking a bone that results in pressure on the nerve.
• Tumors – May irritate or compress the sciatic nerve and produce sciatica; however, this is rarely attributed as one of the causes.
• Pregnancy – Due to carrying a baby there is extra strain on your spine, which can cause sciatic pain.

Sciatica is not just an ailment of the leg and lower back. They are among the symptoms of a more grave disease and it is important to understand the basic nature of the disease to proceed with the treatment on the basis of the present symptoms. Sciatica is basically caused by contraction of a root nerve. However, the condition can arise as a result of a herniated disc, non-aligned spinal cord or a disc that has suffered some serious disorder.

There are chances of encountering the problem of sciatica pain if a woman is pregnant, because the uterus may at times press against the sciatic nerve. Since a woman gains weight during pregnancy, this may result in the nerves being compressed by the vertebrae in the spine. If a woman does not pay attention to her posture during pregnancy, sciatica may occur and pose problems. An improper posture may create pressure on the sciatic nerve. This combined with several other pregnancy related conditions may result in back pain. Another cause of sciatica may also be a muscle spasm in the back. This spasm may be due to the contraction of the piriformis muscle. When this muscle contracts, the muscles may pressurize the sciatic nerve; because of which, a rather painful sciatica may arise. In some cases, the problem of sciatica may be due to sitting for too much longer periods or an incorrect sleeping position, which if not rectified by doing daily stretching exercises, then this may also turn out into a back pain problem.

More pressure on the sciatic nerve is the reason for this back and leg pain. The known reason for backache is a spinal disc herniation. Generally, the nerve passes through the vertebrae. The spinal part is unable to save the nerve in the way it works, if there is herniation. The best treatment for sciatica to get out of the back pain is to remove the firmness. Gradually decreasing the pressure will heal the pressure on the nerves. Normally providing this type of physical sustain to ease the pressure makes this decompression.

Ninety percent of the cases of sciatica are cured with the removal of compression of the disc, so that the disc will relax and recover. Hereditary also plays an important role in a person having a ruptured disc. The treatment is the same for all suffering from this condition. The best treatment is to rest and have a back support. You can also relieve the pain to an extent by means of massage. A professional masseur or masseuse will know the right way to massage the muscles in the areas experiencing the pain and can suggest various exercises that will relieve you from pain.

Both professional massage and self-workouts aim at relaxing the muscles, at the same time reducing the inflammation that must alleviate the back pain fast. The patient may be required to have an extensive period of physiotherapy. If professional treatment is combined with modifications in posture, the person will experience improvement sooner.

It is very important to maintain a body posture so that we can avoid inflammations with our joints. Standing for a long time or sitting in a chair for a long time will not maintain or help improve our posture, rather we should use to have a comfortable seat with a pillow or a soft seat.

By doing just a bit of sciatica stretches every day will also help you get relief instantly.

Sciatic Nerve Pain

What is Sciatic Nerve Pain?

The sciatic nerve pain is also known as sciatica. It is the pain in the leg along with possible tingling, numbness and weakness that travels from the lower back down through the buttock traversing the path of the sciatic nerve.

The most common cause of sciatic nerve pain is a direct trauma to the nerve, usually due to an injection that is given directly given into the buttocks. Prolonged external pressure on the nerve or pressure from the internal body structures can also lead to the pain. Another common cause that can cause pressure on the sciatic nerve is when the pelvis bone is fractured or other similar trauma occurs on the buttocks or thigh. Systemic diseases like diabetes too can damage the sciatic nerve. A ruptured lumbar disc can cause symptoms that can simulate the symptoms of the sciatic nerve dysfunction. This damage leads to the slowing down and gradually preventing the conduction of impulses through the nerve.

The Sciatic Nerve

The largest nerve in the body is the sciatic nerve that is responsible for providing the sensory and motor functions to the lower parts of the body. The nerve provides sensation to the back of the thigh, lower part of the leg and on to the sole of the foot.

Causes – Sciatic Nerve Pain

Some of the common causes of the sciatic nerve pain are:

• Osteophytes: are the additional bone growths that form at the edge of the joints. These bone growths can rub the sciatic nerve causing pain and inflammation.
• Spondylolisthesis: is the condition wherein one vertebra slips forward above the vertebrae below it. This leads to the distortion of the spinal canal and results in the nerve roots of the sciatic nerve to be compressed.
• Herniated Disk: If the outer layer of the intervertebral disk becomes weak or damaged, then the soft center of the disk can protrude out which is known as the herniated disk. These disks can damage any of the 5 origins of the sciatic nerve. Further, chemicals that leak from the center of the disks can also cause inflammation of the nerve.
• Piriformis Syndrome: is an uncommon cause of the sciatic nerve disease. Piriformis is a muscle that lies deep in the buttocks and helps is the rotation and stabilization of the hip. When a person suffers from the piriformis syndrome, the piriformis muscle swells up. This results in the compression of the sciatic nerve present under it.

Treatment – Sciatic Nerve Pain

Majority of the people who suffer from sciatica get better with time with the help of non-surgical treatment which includes one or a combination of the medical or alternative treatments and is usually accompanied with some form of exercise and stretching. The main goal of this kind of treatment is to provide immediate and long term relief and prevention future recurrence of the condition.

But, some people who suffer from more severe cases need surgical intervention. These kind of surgeries are designed to help relieve both the pressure and inflammation and are suggested by doctors if the sciatic nerve pain is very severe and non-surgical treatments have not provided any relief. The traditional treatment is an open back surgery, but this kind of surgery comes with high risks and many related complications. An alternative form of treatment available these days is using laser technology, which is minimally invasive. But, this form of treatment is recommended to people who are suffering with a herniated or a bulging disc that is pressing against the sciatic nerve. Excess disc material is removed which helps alleviate the sciatica pain via microdiscectomy or discectomy.

Pregnant women too suffer from sciatica. This is because the sciatic nerve runs under the uterus and the growing baby can put pressure on it. The best possible remedy is to lie on the side opposite to that of the pain. This will help relieve the pressure on the nerve. Further, lifting heavy weights and standing for ling periods of time should be avoided. Avoiding heat and cold alternatively can also help reduce the pain. Swimming can help ease the discomfort to a large extent. But do consult the doctor before you start swimming. The doctor can also suggest some more light exercises that can help ease the pain.

How To Achieve Sciatic Pain Relief  – The main cause of sciatica is pressure on the nerve at the L4/L5 or L5/S1 area of the spine and this pressure can come from any number of sources and doesn’t necessarily have to end with surgery. 

Sciatic Nerve Pain Relief  – The sciatic nerve pain relief is part of a multi-billion dollar industry. The actual causes of sciatica are not completely understood. Doctors, scientists, and researchers know what causes the discomfort. 

The Main Causes Of Sciatic Nerve Inflammation  – It is not always clear just why and how your sciatic nerve pain may have come about. In fact, even a complete medical exam may not reveal the cause. Oftentimes MRI, xrays and other scans are needed to determine the cause or causes. 

Uncover the Truth of Sciatica Pain  – While there are many causes of sciatica pain, the common factor they share is that somehow the sciatic nerve is being irritated. Most commonly, a spinal disc has shifted and is being compressed, causing pressure on the sciatic nerve.

Sciatic Nerve Pain – What are the Symptoms and Causes?

Sciatica or sciatic nerve pain is a term often used to describe all sorts of back pain. In fact, less than 5% of people who suffer from lower back pain will have sciatica.

Sciatica is caused by a sciatic nerve irritation. This is most commonly caused by a disc bulge in the lower back.

What is the sciatic nerve?

To understand this you need to have a bit of an idea about human spine anatomy. The spine is made up of large bones called vertebra. These bones are separated from one another by spinal discs. Each vertebra overlaps the next at the back to form a joint called a facet joint.

Running down through the middle of the spine is a channel called the spinal canal, its here that the spinal cord sits. The spinal cord is the main structure that passes messages from our brains to our bodies.

At each vertebra the spinal cord braches out to form a nerve root, these nerve roots leave the spine via a gap between each vertebra and then bundle together to form much larger nerves.

In the legs there are two main, large nerves, the femoral nerve at the front and the sciatic nerve at the back. The sciatic nerve passes down through the buttock area into the back of the thigh and leg.

What causes sciatic nerve pain?

The most common cause of sciatica is a disc bulge. The disc is a very misunderstood structure; it has been blamed for back pain ever since it was discovered. Over the years we have started to believe that the disc is a really weak and vulnerable structure.

The term slipped disc makes it sound as if it can slip about inside. In truth the disc cant slip anywhere, it is firmly fixed at the top and at the bottom to the vertebrae above and below.

The disc can and does cause problems however. Sometimes the central area of the disc bulges, usually backwards and sideways. This can cause an irritation of the nerve root as it leaves the spine. Occasionally the bulge is severe enough to actually squash or trap the nerve but this is fairly rare.

When the nerve is irritated by the disc bulge it can become inflamed. Remember what it feels like to hit your finger with a hammer or catch it in a door for a moment. Following the nasty sharp pain you are left with a dull ache. The finger may become red and swollen; there may be some heat or warmth there. After a while, those symptoms settle and everything gets back to normal. Its very similar with the sciatic nerve. It becomes very sore and can give you a lot of pain, even though it is not actually trapped or squashed.

An important thing to know is that many people have disc bulges and have no symptoms at all.

There are some other conditions that can cause sciatic nerve pain but they are much less common. These include degenerative disc disease, severe osteoarthritis, spinal stenosis or spondylolisthesis. Fractures, tumours and infection can also cause sciatica.

What are the symptoms of sciatica?

If someone has true sciatica then they often have pain in the legs, usually in the buttock, back of the thigh or calf. There may also be pins and needles and numbness in parts of the leg.

In severe cases the leg may feel weak and the strength may be reduced. Often, disc bulges cause no back pain at all; the symptoms are felt only in the legs.

Why are so many people given the diagnosis of sciatica?

Very often, as soon as anyone has any lower back or leg symptoms they are told that have sciatica. However, there are other things that can cause leg pain; a strained facet joint for example can cause pain in the buttock and thigh. But if the sciatic nerve is not irritated then it is not sciatica.

The best way to tell if it is sciatica is to undergo a series of test that your physiotherapist or doctor can perform. These simple clinical tests will be enough to identify if the problem is an irritated sciatic nerve.
