Sciatica, or sciatic neuralgia, originates from irritation or compression of the sciatic nerve, the longest nerve in your body. This can lead to pain that travels through your lower back, down your leg, and even to your foot. Everyday activities like sitting, standing, or walking can become a challenge, and if left untreated, this condition can worsen over time.

Many factors can trigger sciatica, from disc injuries to spinal misalignments caused by posture, trauma, or even pregnancy. And while the pain might seem to appear suddenly—whether from bending over or lifting something—the reality is that the underlying spinal issue often develops gradually over time.
