Sciatica pain is cause by when herniated disk, bone spur on the spine, spinal stenosis(narrowing spine) that cause pain, numbness, tingling, weakness in muscle, into hip, buttock, leg, foot, and toes.

What is the symptom of sciatica?
  1. Severe pain, numbness, stabbing, weakness, burning in lower back buttock, leg, feet

  4. mostly occurs in one leg but sometimes occurs in both leg
  5. sudden body movement like sneezing, coughing can make the worsen pain


What is the causes of sciatica?
Sciatica occurs from various medical issues:
  • A herniated or slip disks is a condition in which cushioning Disk supporting between the vertebrae of spine but pressure from the vertebrae effect the center of gel of disk to destroy it outer layer, after herniated disk spinal vertebrae put pressure on your lower back nerves root that cause severe pain like hips legs foot.
  • Degenerative disk is a condition In which the natural degenerate disk between the spinal vertebrae cause shortness of height of disc happened and narrow the passage of nerves roots(spinal stenosis) which cause pinching sciatic nerves roots causes the severe pain In your lower back like hips buttocks legs foot toes.
  • Spondylolisthesis is a disease in which one of your vertebrae slipped out of spinal line by stress fracture or weakness, causes sciatic nerves roots pinch by outline vertebrae cause pain.
  • Osteoarthritis is a condition in which cartilage (supporting tissue between bones) is degenerate naturally which causes compress your lower back sciatic nerve.
  • Tumor inside the spinal canal of lumbar that compress your lower back nerves
  • Piriformis syndrome is a rare neuromuscular disorder in which a flat small muscle is located on the buttock, when it muscles become tight can put pressure on sciatic nerve
  • Cauda equina syndrome is a condition in which cauda equina the bundles of nerves roots after the end of spinal cord which used for your sensory, bladder, bowel, pelvic organs controls is dysfunction and cause pain in legs numbness around the anus, loss of bowel and bladder control.
  • Trauma injury is a sudden physical and shock injury both, this shock injury get immediate treatment since, patients loss muscles power on lower back by any bone fracture, stress fracture or cutting sciatica nerves.


What are the risk factors of sciatica?
Risk factor of sciatica include:
  • Age: In old age people bones start degenerating naturally by the time goes like bone spur, slipped disk are the common cause of sciatica
  • Obesity: obesity is the risk of almost all the disease, its put more pressure to your spine cause stress fracture
  • Occupation: your workplace where you put excess of pressure on your back spine may cause stress fracture like driving, carry heavy loads, etc.

    2. X-ray: doctors ask you for spinal X- ray to check the spinal bone fractures, slipped disk, bone spur, tumor, etc.
    3. Electromyography: to check normal response of muscles and electric impulse travel through the sciatic nerves
    4. Myelogram: to check the vertebrae or disk is causing pain

      • Tricyclic antidepressants
      • Amitriptyline (Elavil)
      • Anti sezure medications


Some alternative techniques are useful for some patient treatment but are not proved with scientist:
  • Acupuncture is techniques in which needles inserted at the specific points at some place making qi, there is flow of some energy qi is channel or meridians which is imbalanced or blockage cause pain, Acupuncture is removed those blockage to maintain qi and reduce pain.
  • Biofeedback is a technique that maintain the body processes like muscle tension, heart rate, blood pressure, the machines collect f data from your body processes, so we can find the specific problem, so patients should control consciously on their own body, mostly common to treat stress
