Piriformis Syndrome and Injury
If sitting in one position for an extended period worsens the symptoms of your sciatica, it may signify that piriformis syndrome is the cause of the pain. Piriformis syndrome is a disorder in the piriformis muscle located in the buttocks, caused by an inflammation or nerve compression. In some cases, symptoms disappear after some time and without treatment, while others manage it as a life-long injury. [9]
What’s more, an injury to your spine may also cause sciatica; for example, a fall from a high point to the ground or hard surface. When you begin to experience the symptoms associated with sciatica after experiencing a fall, it may signify nerve damage, calling for immediate medical attention.
