A slipped disc means that one of the discs of cartilage in the spine is damaged and pressing on the nerves. It’s also known as a prolapsed or herniated disc.
The sciatic nerve is often affected in cases of slipped disc. It’s the longest nerve in the body and runs from the back of the pelvis, through the buttocks, and down both legs to the feet.
If pressure is placed on the sciatic nerve (sciatica), it can cause mild to severe pain in the leg, hip or buttocks.
