SCIATICA HAVE YOU DOWN?
What is Sciatica?
Sciatica is pain in the lower extremity resulting from irritation and pressure of the sciatic nerve. The sciatic nerve is the largest nerve in the body and begins from nerve roots in the lumbar spinal cord in the lower back and extends through the buttock area to send nerve endings down the lower limb.
What does Sciatic Pain Feel Like?
- Pain, burning sensation, numbness, tingling and possible weakness in the leg
- Commonly radiates from the lower back and upper buttock down the back of the thigh to the back of the leg
- Pain may be dull and aching or a ‘shooting’ pain down the leg all the way to the toes
- In severe cases, it can damage nerves and reflexes or cause the calf muscle to deteriorate.
What are the causes of Sciatica?
Pressure on the sciatic nerve can result from a number of causes including:
- Tightness of the piriformis muscle (a deep muscle of the buttock) that compresses the sciatic nerve
- Spinal misalignments, vertebral dysfunction
- Herniated disc, disc prolapse
- Osteoarthritis – osteophyte formation, spinal stenosis
- Poor posture – wearing high heels, prolonged sitting, poor mattress
- Poor lifting technique and poor bending habits
- Spinal compressions due to osteoporosis
