Sciatica is a medical condition that can cause mild to crippling pain. Most commonly, the pain due to nerve compression extends from the lower back down to the hips and buttocks, but the condition can also appear as leg pain and numbness. If you have leg pain, sciatica usually affects only one leg at a time. https://www.newyorkpaincare.com/conditions/conditions-of-the-spine/sciatica-treatment-in-nyc/
