Distinguishing Sciatica From Piriformis Syndrome
Author: admin // Category: Sciatic Nerve Injury
There is considerable confusion regarding the conditions sciatica and piriformis syndrome. Some think that they are the same thing, but although they have very similar symptoms in many cases and can be present simultaneously, the underlying causes of sciatica and piriformis syndrome can be quite different.
Sciatica refers to irritation of the sciatic (often mis-spelled as syatic or psyatic) nerve, that arises from nerve roots in the lumbar spine. The most common cause of sciatic nerve irritation, or "true" sciatica is compression of one or more of its component nerve roots due to disc herniation or spinal degeneration in the lower lumbar region. Depending on the severity of the compression and/or inflammation of the sciatic nerve components, sciatica may extend into the buttock area, into the thigh, or sometimes all the way down the leg to the foot.
Piriformis syndrome is sometimes called false sciatica, because instead of actual nerve irritation, it is caused by referral pain.) caused by tight knots of contraction in the piriformis muscle, which attaches to the upper femur bone and then runs across the back of the pelvis to the outside edge of the sacrum, the triangular pelvic bone at the base of the spine. The symptoms of piriformis syndrome are very similar and may be indistinguishable from true sciatica.
In some cases, piriformis syndrome may cause true sciatic nerve irritation, as the sciatic nerve may run underneath or even through the middle of the piriformis, so contraction of the piriformis may produce sufficient compression of the sciatic nerve to produce actual nerve symptoms. This is one of the main sources of confusion when it comes to distinguishing true sciatica from piriformis syndrome.
As mentioned earlier, the symptoms of true sciatica are very similar to piriformis syndrome. Both cause pain, tingling, burning, "electrical shock" sensations, and/or numbness down the leg, often all the way to the foot. Add to this that the underlying causes of both sciatica and piriformis syndrome can be related to biomechanical problems in the spine and pelvic joints, and the fact that the two conditions can be present at the same time, even doctors may have a difficult time distinguishing between the two.
But since the most effective treatment for the two conditions varies signficantly, it is important to determine the correct diagnosis if at all possible. In most cases there is an easy way to distinguish between sciatica and piriformis syndrome.
Two simple maneuvers will distinguish sciatica from piriformis syndrome in the majority of cases (when the problem is one versus the other and not both conditions at the same time). First, in a seated position, if one straightens the leg on the painful side (so that the leg is parallel to the floor), and the sciatica symptoms increase, this is usually a sign of true sciatic nerve irritation.

The second maneuver is done in two parts. First, from the sitting position one bends the leg and pulls the knee on the painful side towards the same-side shoulder. In all but the most severe cases, there is usually no major increase in pain in this position. The second part of the maneuver is to pull the knee toward the opposite side shoulder. An increase in the sciatica-like symptoms is a strong indication of piriformis syndrome.
It is important to distinguish between sciatica and piriformis syndrome, because the treatment for the conditions varies, and getting the diagnosis right typically leads to more effective treatment.

Due to the lack of MRI or x-ray findings, it may be difficult to diagnose and treat piriformis syndrome. The piriformis muscle connects to the thighbone, assists in hip rotation and is located in the lower part of the spine. When muscle spasms develop in the piriformis muscle thereby compressing the sciatic nerve, Piriformis syndrome develops. The sciatic nerve runs beneath the piriformis muscle. Piriformis syndrome is named for the piriformis muscle and the pain caused when the muscle irritates the sciatic nerve.

The condition of spinal stenosis results in the spinal canal narrowing. The narrowing causes pressure on the spinal cord and spinal nerves. Common in patients over the age of 50 and with causes that are not clear, spinal stenosis has two different types frequently described. A common complaint of spinal stenosis patients is leg pain which gets worse with walking. Another complaint is back pain. Sitting and bending can sometimes alleviate these pains.
g the spinal canal and thus trigger spinal stenosis pain.
Another cause of sciatica is trauma caused by accidents. The impact may injure nerves or cause fragments of bone to compress the nerves (lumbar or sacral spinal nerve roots)
I’m going to share with you some of my favorite exercises to relieve sciatica related pain in the lower back, buttocks, legs and feet. This can be a very painful condition that seems to haunt people with pain no matter what they do. The great thing is there are easy ways to relieve the pain.
There other causes which include when you spinal canal ends up narrowing and puts pressure on the nerves. 15% of people suffer from piriformis syndrome. This is where a nerve runs through the middle a muscle, instead of underneath it. When the , the nerve is compressed and you will feel pain.

The most common cause of sciatic nerve irritation, or "true" sciatica is compression of one or more of its component nerve roots due to disc herniation or spinal degeneration in the lower lumbar region. Sciatica usually begins in the buttock area and, depending on the severity of the underlying nerve comression and inflammation, may extend down the entire leg to the ankle and foot.
