Sciatica: The Most Common Causes

Lower Back Pain

A couple of lower back or lumbar spine disorders could cause sciatica and spinal nerve compression. However, the most culprits include the following:

Herniated Disc

This happens when your nucleus breaks through your annulus fibrosus, causing the disc material pressing on a nearby nerve root, thereby compressing soft nerve tissues and causing sciatica. When this occurs, aside from directly compressing your nerve root against your spinal canal’s interior, your disc material will likewise release hyaluronic acid, which is a chemical irritant that causes inflammation.

Trauma

Sciatica could likewise be caused by direct compression of the nerve due to external factors to the nerve roots of your sacral or lumbar spine. Common examples of trauma include sports injuries, most particularly from contact sports like football, falling down, and car accidents. The impact of these injuries might injure your nerves or broken bone fragments might compress your nerves, says one of the most sought-after injury chiropractors in Denver.

Spondylolisthesis

This is a disorder that usually impacts the lumbar spine and occurs when one vertebra slips forwards and over a neighboring vertebra. When this happens, the vertebra will remain displaced and would lead to compression of the spinal nerve roots, which in turn causes sciatica.

Piriformis Syndrome

This is characterized by muscle spasms in your piriformis muscle, which in turn compresses your sciatic nerve. This muscle could be found in your spine’s lower section, connects to your thigh bone, and helps in rotating your hips. Your sciatic nerve is located under this muscle.

Lumbar Spinal Stenosis

This is a nerve compression disorder that usually affects older adults. The pain is commonly positional and triggered by walking or standing for long periods of time and is typically alleviated by resting and sitting down.

Spinal Tumors

These are unusual growths that could either be benign or malignant/cancerous. Although spinal tumors are rare, when these develop in your lumbar region, sciatica almost always also develop because or nerve compression.

Determining if you have sciatica could be difficult because it will be dependent on figuring out what’s causing it in the first place. That being said, if you feel that you might have sciatica, you must get a proper diagnosis of the underlying cause first so you could work towards alleviating your pain symptoms.
