It originates from lumbar to the butt and radiates down to the back of the leg. The discomfort can be felt anywhere on the nerve path, but especially from the lower back to your butt and also at the back of your calf and thigh.
It can be mild or a piercing pain, burning sensation or extreme pain. At times, it can be like an electric shock. It worsens when the affected person coughs or sneezes. Sitting for a long time can also worsen the pain. Normally, it affects one side of the body.
Numbness, weakness, or a tingling feeling will be felt in the foot when you have sciatica. And sometimes, it might cause pain in one part and make you feel numb in another.
