When the sciatic nerve is compressed or irritated, it can cause pain, numbness and a tingling sensation that radiates from your lower back and travels down one of your legs to your foot and toes. The pain can range from being mild to very painful, and may be made worse by sneezing, coughing, or sitting for a long period of time.
Some people with sciatica may also experience muscle weakness in the affected leg. While people with sciatica can also have general back pain, the pain associated with sciatica usually affects the buttocks and legs much more than the back. Most people find their sciatic pain goes away naturally within a few weeks, although some cases can last for a year or more.
In the vast majority of cases, sciatica is caused by a herniated or slipped disc. This is when one of the discs that sit between the bones of the spine (the vertebrae) is damaged and presses on the nerves. Less common causes include spinal stenosis (narrowing of the nerve passages in the spine), a spinal injury or infection, or a growth within the spine (such as a tumour).
You can minimise your risk of developing a slipped disc or back injury that could lead to sciatica by adopting a better posture and lifting techniques at work, as well as stretching before and after exercise, and exercising regularly.
Treating Sciatica :
Many cases of sciatica will pass in around six weeks without the need for treatment.
However, it will help you to exercise and use hot or cold packs. Consider reflexology to reduce the inflammation in your spine, and relieve the pain. Revs reflexology shoes will also help with your posture, with the built-in orthotic arch support, the elastomer and cushioned sole, taking the pressure of the spine.
