Leg pain can be due to a problem with bones, tendons, muscles, fascia, nerves, blood vessels, or skin disorders. Your physician may direct you for a Pedorthic evaluation if a biomechanical influence is suspected. Common issues seen are overloading of a muscle or muscle groups trying to counter or stabilize excessive motions. Excessive pronation is commonly attributed to overworked muscles in the leg such as tibialis posterior or tibialis anterior. It’s counter movement is called supination where the foot tends to lean outward. Muscles often overloaded when this motion becomes excessive are the peroneals.
Excessive twisting motions of the large leg bone, the tibia, while walking or running can lead to higher torsional stress. In some cases this may lead to a stress fracture. Sharp intense leg pain in the bone, found commonly in the lower 3rd of the leg, that is irritated with activity may indicate a stress fracture. These symptoms should not be ignored and should be assessed immediately.
