What are The Causes of Sciatic Nerve Pain?
Sciatica is a medical condition where the sciatic nerve becomes irritated and cause pain. The sciatic nerve is a collection of nerves that emerge from the lowest part of the spine. The sciatic nerve is the biggest and longest nerve. It originates from the lower back, travels through the gluteal (buttocks) as it makes its way towards the thigh and leg.
Fibers from five spinal nerves on each side of the spine come together from spinal segments of L4-S3 to form the sciatic nerve. Compression of nerves at L4, L5, S1, S2 or S3 can lead to symptomatic or painful sensation known as sciatica. However, sciatica also results when compressed at the buttocks. Muscle spams at the buttocks, specifically the piriformis muscle is a known cause of sciatica.
In essence, once the nerve has been compressed and aggravated, it starts to send signals of pain. The severity of pain varies from individual to individual. For example, some people note mild pain while others have a more severe form.
