Leg pain has many causes. "Sciatica" is a common type of leg pain that is caused by nerves being irritated in the spine. That type of pain may involve a sharp shooting sensation or numbness and tingling. Other nerves in the leg can cause nerve pain as well.
There are many other causes of leg pain though. The pain could come from the bone if there is a fracture. It could come from the joints such as in arthritis. Or it could come from the muscle, which may happen in people who have thyroid problems.

This is more common in smokers, diabetics, and people with high blood pressure or high cholesterol.
