Intervertebral discs (AKA: "shock-absorbers" of the spine) are the cartilage cushions located between the vertebrae (bones) of the spine. Discs can become inflamed, irritated, bulging, and even ruptured if the spine undergoes even the most trivial of traumas. The most common signs that a person may be suffering from a disc problem are numbness and tingling through their arms and legs, often accompanied by sharp shooting pains. Discs that are bulging or pinching on a nerve exiting the spinal column can be a very serious condition directly linked to subluxations (spinal misalignment). Often diagnostic imaging in the form of x-rays and MRIs are needed to properly diagnosis a disc problem condition.
