Sciatica is the name given to leg pain, numbness and tingling that results from increased pressure on the sciatic nerve, which branches off of the spinal cord just below the pelvic girdle. Not a diagnosis of its own, sciatica may the result of a number of other medical conditions.
Potential Causes of Sciatica
Increased pressure on the sciatic nerve may result from:
- Degenerative conditions, including:
- Disc disease
- Lumbar spinal stenosis
- Injury or irritation of the structures of the lower back, such as:
- Isthmic spondylolisthesis
- Piriformis syndrome
- Sacroiliac joint dysfunction
- Herniated disc
- Muscle strain
- Increased weight, including temporary weight gain associated with pregnancy
Excessive impact may be the underlying cause of many injuries that give rise to sciatica, but regardless of the cause of sciatica, excessive impact will exacerbate the symptoms.
Treatment for Sciatica
Because pressure on the sciatic nerve causes sciatica, effective pain relief comes from reducing that pressure. Sciatica treatments often include anti-inflammatories, including cortisone shots, to reduce swelling in the area. When sciatica is caused by a temporary injury and natural healing will eliminate symptoms, the temporary relief these treatments provide is enough. However, if sciatica is caused by a degenerative condition, surgery may be considered for permanent pain relief.
Because impact is a cause and/or exacerbating factor of sciatica, effective pain relief may also be achieved with shoes that deliver significant impact reduction—Z-CoiL® Pain Relief Footwear®.
