What is sciatica?
Sciatica is when the sciatic nerve, which runs from your hips to your feet, is irritated. It usually gets better in 4 to 6 weeks but can last longer.
Sciatica is a common condition and can also be known as nerve root or radicular pain. Sciatica is a term used to describe pain felt in the leg but which often comes from the lower back.
The sciatic nerve starts in the lower back and goes all the way down the back of the leg into the foot. Symptoms can be experienced along any part of the nerve. They can have a sudden or slow onset and can vary from mild to severe1.
The pain can vary between a mild ache, to a sharp burning pain. Sometimes it can feel like a jolt or electric shock2.
