SCIATICA

Sciatica is a condition characterized by pain, numbness, tingling, or weakness in the lower back and legs, typically affecting the sciatic nerve.

What is the Sciatic Nerve?

The sciatic nerve is the longest nerve in the body, extending from the lower back (lumbar spine) to the legs. It consists of five nerve roots:

1. L4 (lumbar 4)

2. L5 (lumbar 5)

3. S1 (sacral 1)

4. S2 (sacral 2)

5. S3 (sacral 3)

Causes of Sciatica:

1. Herniated discs

2. Degenerative disc disease

3. Spondylolisthesis (slipped disc)

4. Spinal stenosis (narrowing of the spinal canal)

5. Piriformis syndrome (muscle compression)

6. Trauma or injury

7. Tumors or infections

8. Poor posture or biomechanics

Symptoms of Sciatica:

1. Pain or burning sensation in the lower back, buttocks, or legs

2. Numbness or tingling in the legs or feet

3. Weakness or fatigue in the legs

4. Difficulty walking or standing

5. Pain worsened by sitting, bending, or lifting

How Sciatica Works:

1. Compression or irritation: Sciatic nerve is compressed or irritated.

2. Inflammation: Body's natural response to injury leads to inflammation.

3. Pain signaling: Nerve sends pain signals to the brain.

4. Muscle spasms: surrounding muscles contract, exacerbating pain.

Diagnosis of Sciatica:

1. Medical history

2. Physical examination

3. Imaging tests (e.g., X-rays, MRI, CT scans)

4. Electromyography (EMG)

5. Nerve conduction studies

Treatment Options for Sciatica:

Conservative:

1. Rest, ice, compression, elevation (RICE)

2. Physical therapy

3. Pain management (medication, injections)

4. Chiropractic care

5. Stretching and exercises

Surgical:

1. Discectomy (disc removal)

2. Microdiscectomy (minimally invasive disc removal)

3. Laminectomy (spinal canal expansion)

4. Spinal fusion

Prevention Strategies:

1. Regular exercise and stretching

2. Proper posture and biomechanics

3. Regular breaks and stretching during activities

4. Maintaining a healthy weight

5. Avoiding heavy lifting or bending

When to Seek Medical Attention:

1. Sudden severe pain

2. Difficulty walking or standing

3. Numbness or tingling in the legs or feet

4. Weakness or fatigue in the legs

5. Recent trauma or injury

Consult an orthopedic specialist or primary care physician for proper diagnosis and treatment.

Sciatica Classification:

1. Acute sciatica (less than 6 weeks)

2. Subacute sciatica (6-12 weeks)

3. Chronic sciatica (more than 12 weeks)

Sciatica Complications:

1. Permanent nerve damage

2. Chronic pain

3. Muscle atrophy

4. Decreased mobility

5. Depression or anxiety

Sciatica Facts:

1. Affects 40% of adults at some point in their lives

2. Most common age range: 30-50 years

3. Male-to-female ratio: 2:1

4. 90% of cases resolve within 6 weeks

Sciatic Nerve:

1. Longest nerve in the body (up to 20 inches)

2. Originates in the lumbar spine (L4-S3)

3. Divides into two branches:

    - Tibial nerve (leg and foot)

    - Common peroneal nerve (leg and foot)

Causes of Sciatica:

1. Herniated discs (60-90%)

2. Degenerative disc disease

3. Spondylolisthesis (slipped disc)

4. Spinal stenosis (narrowing of the spinal canal)

5. Piriformis syndrome (muscle compression)

6. Trauma or injury

7. Tumors or infections

8. Poor posture or biomechanics

Symptoms:

1. Pain or burning sensation in the lower back, buttocks, or legs

2. Numbness or tingling in the legs or feet

3. Weakness or fatigue in the legs

4. Difficulty walking or standing

5. Pain worsened by sitting, bending, or lifting

Stages of Sciatica:

1. Acute (0-6 weeks): Pain and inflammation

2. Subacute (6-12 weeks): Pain and stiffness

3. Chronic (beyond 12 weeks): Persistent pain and limited mobility

Diagnosis:

1. Medical history

2. Physical examination

3. Imaging tests (e.g., X-rays, MRI, CT scans)

4. Electromyography (EMG)

5. Nerve conduction studies

Treatment Options:

5. Avoiding heavy lifting or bending

When to Seek Medical Attention:

1. Sudden severe pain

4. Weakness or fatigue in the legs

5. Recent trauma or injury

Consult an orthopedic specialist or primary care physician for proper diagnosis and treatment.

Sciatica Exercises:

1. Knee to chest stretch

2. Piriformis stretch

3. Hamstring stretch

4. Hip flexor stretch

5. Pelvic tilt

Sciatica Home Remedies:

1. Heat or cold therapy

2. Over-the-counter pain relievers

3. Rest and relaxation

4. Stretching and exercise

5. Ergonomic adjustments (e.g., chair height, lumbar support)
