A: Your grandfather is partially correct. Discs do not slip, but they do herniate. Thus, if you want to be accurate, you can call such a condition a herniated nucleus pulposus.
An important job of spinal discs is to separate and cushion vertebras from one another. About one-half inch thick, they are made of a strong rubbery material which allows them to compress and absorb the shocks your spine takes as you move about.
Sometimes a disc herniates or bulges and presses spinal nerves. This is the condition commonly called a slip disc.
Urgent pain is the chief symptom of a herniated disc. The pain can span the scale from a dull ache to a sharp, unremitting pain —- usually in the low back — sometimes extending into the buttocks and sometimes down the leg. Movement may make the pain worse.
Numbness in the legs, tingling and “pins and needles” feelings are sometimes present. Pain is the chief symptom and calls for an examination at once to determine its cause. Chiropractic care can help reduce the pain and discomfort by aligning the spine in its natural position, thus decreasing the pressure on the disc and nerve.
