Leg pain is a common complaint, with many possible causes. Two of the more common causes are trigger points in the IT band or the psoas muscle. The IT band is a band of tissue that runs along the outside of the leg from the hip to the knee. It can become irritated and inflamed, causing pain in the leg. The psoas muscle is a large muscle that runs from the lower back to femur. It can also become inflamed and trigger pain in the leg. Other possible causes of uncomfortable feelings include arthritis, shin splints, and nerve compression. If you are experiencing leg pain, it is important to see a doctor to determine the cause, but also to schedule a massage to release the tight muscles.
