Sciatica refers to a condition characterized by pain that radiates along the path of the sciatic nerve, which runs from the lower back through the hips, buttocks, and down each leg. This pain typically results from compression or irritation of the sciatic nerve, often caused by a herniated disc, spinal stenosis, or other underlying conditions. Sciatica can manifest as a sharp, shooting pain, tingling, or numbness, and its severity can vary, impacting daily activities and mobility.

Products used to treat sciatica often include lumbar support cushions and ergonomic chairs to promote proper spinal alignment, reducing pressure on the sciatic nerve. Additionally, specialized pillows for leg elevation, heat wraps, and TENS (transcutaneous electrical nerve stimulation) units are commonly employed to alleviate pain and discomfort associated with sciatic nerve compression, providing targeted relief for individuals managing this condition.
