The pain can vary between dull, aching or burning sensations and sharp, shooting pains. Sciatica causes pain that usually begins in the lower back and spreads through the buttock, leg, calf and, occasionally, the foot. It may happen due to the effects of general spine wear and tear ( spondylosis) or a traumatic injury that causes sudden pressure on the lumbar discs (e.g. You’re most likely to get sciatica when you’re 30 to 50 years old.

While there are numerous causes of sciatica, the most common are: Anything that irritates or compresses the sciatic nerve can cause sciatic pain. Otherwise, joint inflammation, nerve compression from bony arthritic growths or a locked facet joint in the lower spine can cause sciatica. Pressure on the sciatic nerve from a herniated disc is usually what causes sciatica. Sciatica is commonly misdiagnosed, which can result in either slow or non-responsive treatment. Irritation or pinching of your sciatic nerve can cause severe leg pain known as sciatica. The main nerve that travels from your lower back to your leg is your sciatic nerve. It can be a local leg injury, or it may even be referred from your lower back. The sciatic nerve originates from spinal segments L4, L5, S1, S2 and S3. The sciatic nerve is the longest in the body, which runs from your lower back down through the buttock, hamstrings, and lower legs. Sciatica describes pain felt along the sciatic nerve, and anything that irritates or compresses the nerve can cause sciatic pain.
