Sciatica is a broad spectrum term commonly used to describe pain running down the leg originating from the lower back, typically following the sciatic nerve pathway. Sciatica is usually due to some form of compression or ‘pinched nerve’ at the spine, commonly by a herniated/’slipped’ disc or encroaching arthritis, but can be caused by many things that can irritate the nerves and nervous system. Sciatica usually refers to one leg but can also refer to both in certain cases. It can present in many ways but people who suffer from sciatica use terms such as ‘sharp shooting pain’, ‘tingling’ ‘burning’, ‘aching’ and ‘throbbing’ pain most commonly.
Lower limb pain can be caused by local problems relating to the joints, muscles, ligaments and tendons. However, it can also be the result of irritation to the nerves of the lower back.
‘Pinched Nerves’ can also occur in the neck and upper back, causing similar types of pain into the arms and hands.
Vertebral subluxations of the lower back can disrupt the nerve signals that supply the lower limb, thereby producing pain and dysfunction.
