What’s Really Happening?
Typically, the disc tends to distort and derange at the back of the disc. This is due to the way most people in our society bend through their low back. (Bending forward without bending through the hips and knees as in a squat).
The way we sit also causes increased pressure on the lumber discs. Modern human sits a lot. The flexed spine (bent forward) movement forces the nucleus inside the disc (its soft inside bit) backwards - like a donut being squashed in a press from the front. The donut's soft middle bit would likely come out the back end of the disc.
It is the same principle with the disc itself, except it usually happens over time. The person would usually first notice a small twinge or stiffness after getting up from a chair. Or discomfort first thing upon getting up in the morning. These are usually the first warning signs of altered bio-mechanics causing damage. This usually happens when the disc damage or derangement starts to encroach on the area of the outer 1/3 of the disc.
These signs can come and go over an extended period and may even go away and then one day, the person has an acute episode usually in the form of stabbing pain and muscle spasm. If the disc bulges or rips into the outer 1/3 of the disc or beyond, the pain can be excruciating. It often occurs with some benign movement “ I reached for a pencil” . The person would describe a pain that took their breath away and that they couldn’t stand up straight. Some also complain of leg pain.
If the bulge in the disc is large enough to reach the nerve roots exciting the spine the person will experience sciatica.
