Sciatica refers to the severe pain that radiates along the path of the sciatic nerve, often described as “lightning” in nature, and travels from the lower back to the back of the knee and then to the bottom of the sole. It could also present as deep aching pain, burning pain, or pins and needles (paraesthesia).
It is usually caused by a slipped, herniated disk (prolapsed intervertebral disc) resulting in impingement of the nerve. Depending on the size and location of the slipped disc, the most severe form can result in loss of functions of the lower limbs and the control of bower and bladder (Cauda Equina Syndrome). Due to the level of pain involved, sciatica treatment is highly advised in Singapore.
