Sciatica is a condition characterized by pain that radiates along the sciatic nerve, which runs from the lower back down the legs. It is often caused by a herniated disk, spinal stenosis, or nerve compression. Symptoms of sciatica include sharp pain, numbness, tingling, and weakness in the affected leg. Treatment options for sciatica may include rest, physical therapy, pain medication, and in some cases, surgery. Additionally, exercises and stretches that target the affected area can help alleviate symptoms and prevent future episodes of sciatica. Seeking medical advice is crucial for accurate diagnosis and appropriate treatment.
