The term ‘slipped disc’ can be very misleading.
Rather than using the word ‘slipped’, ‘bulging’ is more in line with what is actually happening in this scenario.
A ‘bulging disc’ is the result of significant pressure from the muscles squashing the disc. This disc then bulges out into the openings between the vertebrae which lie between the discs, and this creates pressure on the nerves.
Irritation to the spinal nerves of the lower back may result in back pain and this may be referred along the nerve pathways into feet, legs, groin and abdomen. Often pain is felt along the large Sciatic nerve which passes through the buttock and down the back of the leg.
Attending to the lower back and releasing the muscle tension allows the pressure on the discs to withdraw and once this happens the disc will no longer be pinching the spinal nerve roots.
