Sciatica may occur if you have a protruding (herniated) disk in your spinal column that is pressing on the nerve roots in the lumbar spine. It is often identified by a sensation of pain in your lower back or hip that radiates to the back of your thigh and into your leg. The pain is usually sharp and may feel like a cramp. You may also experience weakness, “pins and needles” sensations, numbness, or burning/tingling sensations down your leg. You are more likely to be diagnosed with sciatica between the ages of 30 and 50 years. It may happen as a result of the general wear and tear of aging, or any sudden pressure on the disks that cushion the bones (vertebrae) of your lower spine.
