What is sciatica?

Sciatica refers to pain that radiates along the path of the sciatic nerve, a large nerve extending from the lower back and branches down the back of each leg. Typically sciatica affects only the side of the lower body but depending on where the sciatic nerve is affected, the pain can also extend down to the foot.

Pain that goes from your lower back through your buttock and down your leg-foot could be sciatica. Nerve pain related to a compression of the sciatic nerve usually affects only one side of your body, but can also radiate to both legs (lower limbs). 

A slipped disc or herniated disc is a condition when a soft cushion (cartilage) of tissue between the bones in your spine pushes out. This is painful if it presses on nerves, especially the sciatic nerve in the low back area. 

The cause is the usual age-related wear and tear of the discs. Spinal discs lose some water as you age, which makes them more prone to tear or rupture due to a strain. This can lead to pain, numbness and sometimes weakness in the leg.

Risk Factors:

Main risk factors for sciatica includes:

  • Age: herniated disks can happen at adult or older age, causing the typical sciatic pain; but disc degeneration, bone spurs and lumbar stenosis (narrowing of the spinal canal and foramen), which can cause pain, numbness and even weakness to one or both legs, are more common among older people.

  • Sedentary lifestyle: people who sit for prolonged periods or have a sedentary lifestyle are more likely to develop sciatica than active people are.

  • Smoking cigarettes: increases your risk of having disc disease.

  • Lifestyle: it’s suspected that twisting your back, lifting heavy weights and bad posture may lead to sciatica.

Signs & Symptoms:

Sciatica symptoms could include some of the following:

  • Pain that radiates from your lower spine to your buttock and down the back of your leg and foot is a typical symptom of sciatica.

  • The pain may range from being quite mild to severe. Some people experience it like an electric shock.

  • The pain is often aggravated by coughing, sneezing or sitting for a long period.

  • Some people have numbness, tingling or weakness in the affected leg or foot.

Diagnosis:

At Medcare, a spine specialist will start to assess the patient with a medical history, physical exam, checking for muscle strength, sensation and reflexes. If necessary, imaging tests may be required. You may be asked to have an x-ray, MRI, CT scan and/or electroneuromyography (ENMG) for the proper diagnosis.

Treatment Options:

The spine specialist will give you a plan for your low-back pain radiating to the leg and/or foot (lumbosacral radicular pain) treatment, according to the case. This plan could include medications, such as: anti-inflammatories, painkillers and muscle relaxants, physical therapy, pain clinic and spinal injections.

If the patient does not improve with conservative treatment, our spinal surgeons can proceed with the required surgical treatment to alleviate their sciatic problem due to lumbar disc herniation or related problem.

The main indications for surgery for cases of lumbar disc herniation are the following: significant and persistent pain to the leg and/or foot, weakness of the lower limb, and in more severe cases, loss of bowel and/or bladder control (cauda equina syndrome). The spine surgeon usually use microsurgical technique to remove part of the herniated disc to decompress the sciatic nerve (lumbar decompression and microdiscectomy).

FAQs:الأسئلة الشائعة:
  • How can I prevent lumbar disc problems which can cause sciatica?

    A: Follow general good practices to protect your back. Exercise regularly and strengthen the core muscles in your back and abdomen. Avoid smoking, as some of the smoke components can interfere with the blood supply to the discs and predispose to disc diseases. Maintain good posture and use chairs that provide lower back support. When lifting weights, take care that your back is not strained.

  • Is it better for me to rest or to exercise, for my sciatica?

    A: There are exercises that can relieve the pressure on the sciatic nerve. Meet a physiotherapist at Medcare for the best physiotherapy for sciatica. Walking is usually helpful as well, as it releases endorphins that give relief from pain and reduce inflammation, but you should try to avoid painful activities.
