Part 3

SCIATICA
Pain in the low back and leg (fig. 12 a,b,c) Is the most common symptom with pain during movement. The inability to bend and twist the low back is very evident. The amount of pain depends upon the severity of the disc protrusion. The pain in the low back and leg may be sharp stabbing pain, extending with seeing agony from the low back to the foot, or it may be of less severity representing a dull ache. The pain may be felt in the back or any area of the lower extremity supplied by the sciatic nerve. Usually, the pain is in one leg. The pain may be described as any of these sensations: burning, numb, pins and needles, worms crawling in the skin, tingling, or a feeling that someone has your leg in a vise and squeezing it. In severe cases, inability to move the leg may be evident.
