Sciatica is commonly misdiagnosed, which can result is either slow or non-responsive treatment. Leg pain can have various sources. It can be a local leg injury or it may even be referred from your lower back. The main nerve that travels from your lower back to your leg is your sciatic nerve. Irritation or pinching of your sciatic nerve can cause severe leg pain known as sciatica. Common Causes of Sciatica Pressure on the sciatic nerve from a herniated disc usually causes sciatica.
