Sciatica typically occurs due to:

• Herniated discs – When a spinal disc slips out of place, pressing on the nerve.
• Spinal misalignments – Vertebrae shifting out of position, pinching the nerve.

What Leads to These Issues?
Trauma – Car accidents, sports injuries, or falls


Repetitive strain – Heavy lifting with poor posture (common in labor jobs or gym-goers)


Prolonged Sitting – Desk jobs or sedentary lifestyles increase pressure on the nerve


Aging – Natural disc degeneration weakens spinal support


Excess Weight – Adds stress to the spine and nerves


Chronic Conditions – Osteoarthritis, spinal stenosis, or degenerative disc disease

Sciatica vs. Other Nerve Compression


Sciatica is just one type of nerve compression—similar issues (like carpal tunnel syndrome) can affect other nerves, causing localized pain. Some patients also experience sciatica alongside conditions like fibromyalgia, intensifying discomfort.

This happens for many reasons, but typically Sciatica is caused by:

• A herniated disc. This is when one of the spinal discs is displaced from its normal area, putting pressure on the Sciatic nerve.
• A vertebral misalignment. This is when one of the spinal vertebrae moves out of its correct position, pressing on the nerve.

A slipped vertebrae or herniated disc can be caused by:

• A traumatic event, such as a sports injury or auto-accident
• Lifting heavy objects repetitively with bad posture. This is common with manual labor workers, or individuals who exercise regularly at the gym.
• Microtraumas such as sitting at a computer daily for many hours for months or years. The sitting position applies the most pressure to the Sciatic nerve.
• Aging. As the spine ages, the discs naturally become weaker, applying more pressure on the exiting nerves.
• Being overweight. Additional weight adds more stress and strain to our spine, joints and nerves.
• Chronic conditions like Osteoarthritis, Degenerative Disc Disease and Spinal Stenosis.

It’s important to realize that Sciatica is only one specific example of nerve pinching in general. Nerve pinching can happen to many other nerves, such as the median nerve – which results in the well-known carpal tunnel syndrome.
In any case of nerve pinching, you may feel symptoms similar to Sciatica but localized in the area of the affected nerve.
Additionally, some patients can experience Sciatic nerve pain with other conditions simultaneously, such as Fibromyalgia, making pain much more severe
