@anatomyunseen1: Sciatic nerve pain starts in the lower spine. When a spinal disc bulges or shifts, it can press against the sciatic nerve, the largest nerve in the human body. This pressure sends pain signals traveling down the nerve — often from the lower back all the way to the leg or foot. That’s why sciatica pain can feel like burning, tingling, or shooting pain down one leg. #sciatica #nervepain #spinehealth #anatomyexplained #medicaleducation
