The underlying causes can be as various as its symptoms. However, some of the most common instigators are:
As discs in the spine age, they begin to show wear and tear. This process can be accelerated by other factors and may cause sciatica as your spinal makeup begins to change.
Also known as a “slipped” or ruptured disc, a herniation occurs when a tear in the disc’s hard outer layer, known as the annulus, allows the inner liquid-like nucleus to leak into the spinal canal. Pressure results and, if located near the sciatic nerve, can lead to sciatica. Herniated discs usually happen because of strenuous labor or everyday tasks that are physically straining.
Sciatica may be caused by spinal stenosis, or the narrowing of the spinal canal. When spinal stenosis occurs, tension is placed on the spinal cord and may irritate and strain local nerves.
The slim piriformis muscle is located in the buttocks, near the hip joint, and helps people move their thighs, maintain balance and walk. The sciatic nerve travels closely to this muscle and can easily become pressed or irritated when the piriformis spasms or contracts. Runners and other athletes are especially susceptible to this type of trigger.
Occasionally, a vertebra in the spine can slip forward and slide over the bone beneath it. This condition is known as spondylolisthesis and is most common in the lower back, where straining nearby nerves can cause sciatica.
Some unexpected traumatic events, such as a car accident, can lead to sciatica. Injuries sustained and new scar tissue can place stress on the sciatic nerve.
During pregnancy, pain in the back of the thighs spurred by shifts in the pelvic region can be misdiagnosed as sciatica. However, there are situations in which the sciatic nerve is actually being pressed as a result of these changes. Speak to your doctor if you think you are suffering from sciatica or pelvic groin pain.
Rarely, an infection in the spine may cause sciatica.
Growths and related health issues may irritate the sciatic nerve and lead to chronic sciatica.
Symptoms often include:
If conservative treatments do not ease your sciatica-related pains, you may consider undergoing minimally invasive surgery. Minimally invasive procedures focus on removing the condition instead of only treating the symptoms. These approaches also prioritize extremely small incisions and shortened recovery times.
An Endoscopic microdiscectomy involves trimming and removing fragments of intervertebral discs that have broken away and are pressing on the sciatic nerve or spinal cord.
Sometimes, a portion of the arthritic vertebral bone and thickening of the ligament inside the spinal canal will be trimmed or removed to curtail sciatica.
