Sciatica
Sciatica is pain that radiates through the path of sciatic nerve. The sciatic nerve is the longest nerve of the body. Its route start from the spinal cord to the buttock and hip area and then it runs down the back of each leg. It usually occurs as an outcome of irritation or compression to the nerve such as from a bulged, prolapsed or a herniated disk. It is a relatively common form of low back and leg pain.
Causes
- Sciatica is mostly caused by disc herniation or stenosis from spinal asymmetry.
- It affects lumbar or sacral nerve roots.
- Fixing spinal alignment can heal the disc and reduce symptoms.
- The sciatic nerve passes through or under the piriformis muscle.
- Piriformis muscle spasm can press on the nerve (piriformis syndrome).
- In piriformis syndrome, the nerve root is normal.
- Pregnancy can cause sciatica due to pressure from the baby.
- Accidents can misalign the spine and cause sciatica.
Signs and symptoms
- Pain from lower back to buttock, back of thigh, and calf
- Muscle weakness or numbness in leg or foot
- Tingling or pins-and-needles sensation in toes or foot
- Reduced muscle mass in calf or thigh
- Pain in one part of the leg, numbness in another
- In severe cases, loss of bladder or bowel control
PMC Diagnosis
- Diagnosis is based on medical history and physical exam.
- 3D spine X-rays are commonly used.
- Typical signs include radiating leg pain and nerve-related symptoms.
- Straight leg raise test is positive in about 90% of cases.
- Imaging like CT or MRI may be used to confirm disc herniation or stenosis.
- Diagnosis is often made by a certified orthopedic surgeon
PMC Treatment/ Precautions
- Spinal realignment is essential for managing sciatica, as misalignment causes 90% of cases.
- PMC treatment effectively repositions the spine and supports tissue regeneration.
- Lifestyle changes are important alongside PMC treatment.
- Sleep on a firm, comfortable mattress on your back or side with knees bent.
- Use a pillow under or between knees for support.
- Choose the sleeping side that feels more relaxing.
- Adjust chair height so feet are flat on the floor and knees are slightly above hips.
- Avoid crossing legs while sitting.
- Use chairs with firm back support and sit upright.
