Sciatica Pain

Common Causes of Sciatica

There is number of lumbar spine disorders that cause sciatica. Sciatica is known as a mild to intense pain, which can be felt in the right or left leg. There are also instances where both legs are affected by the pain. Sciatica is due to the compression of nerves in a person’s lower back. 

Causes of Sciatica PainAnother term used by doctors is Radiculopathy. It is a medical term, which describes weakness, tingling, numbness, and pain in the legs or arms, which is caused by the nerve problem. Now, when the pain is in the neck and is caused by the nerves, then this is called cervical radiculopathy. Since the lower back is the one affected by sciatica, it is then known as lumbar radiculopathy.

Sciatica Nerve Pain

Causes of Sciatica PainThe sciatic nerve is made out of 5 sets of nerve roots, which is located in the lumbar spine. This nerve starts at the back of sacrum and runs through the back of the buttock, through the hip until it reaches the leg. These nerve roots may not be structures that are solitary, but they are part of the nervous system, which can transmit pain. It can also transmit different kinds of sensation in different parts of the body. Sciatica pain occurs when the nerve is being compressed. 

There are common causes of Sciatica that you should know about. Let’s get to them now and get to know each:

Herniated Disc

Causes of Sciatica PainOne of the most common causes of sciatica is a herniated disc. This kind of problem happens when the nucleus breaks through the body’s annulus fibrosus. This problem can press the nerve root and the nerve tissues that are delicate, which can then cause sciatica. A herniated disc can also cause nerve inflammation because the disc contains a chemical and acidic irritant. Besides extreme pain, an individual can also feel muscle weakness, tingling, and numbness.


Causes of Sciatica PainSpondylolisthesis is known as a disorder that can affect an individual’s lumbar spine. It is often characterized by a single vertebra that is slipping forward over a vertebra that is adjacent. Now, when the vertebra slips and becomes displaced, the spinal nerve root will get compressed. This will then cause sciatica pain in the leg. Spondylolisthesis can be developed during childhood or even at birth. Sometimes it can also be from spinal degeneration, physical stress, or trauma.

Lumbar Spinal Stenosis

Causes of Sciatica NerveSpinal Stenosis is known as a nerve compression disorder, which can affect older adults. Due to this disorder, leg pain can occur, which can be mistaken for sciatica. The pain felt is positional, wherein it can be brought by certain activities like walking or standing. The pain is then relieved by sitting down.

Piriformis Syndrome

Causes of Sciatica PainPiriformis syndrome is the pain that is caused by the piriformis muscle. This muscle can be found in the spine’s lower part. It is connected to the thighbone and helps in the rotation of the hip. The sciatic nerve usually runs in the piriformis muscle, and when muscle spasms occur, it will compress the sciatic nerve, which can cause pain. 

These are some of the most common causes of sciatica pain. If you’ve been experiencing sciatica pain, then consulting your doctor about this is ideal. In this way, he can help you in treating the pain and give you back the pain free life that you deserve.
