The most typical cause of sciatica is a compressed portion of the nerve caused by a herniated disc or a bone spur on the spine. Additionally, it could be brought on by any pressure placed on the nerve anywhere along its course. In the affected leg, this results in inflammation, discomfort, and frequently some numbness. Even though sciatica pain can be extremely painful, the majority of cases get better in a few weeks with only conservative therapies. After six weeks of therapy, those who still experience acute sciatica may benefit from surgery to release the strain on the nerve.
