Fatigue fractures occur mainly in the lower part of the tibia and the metatarsal bones of the foot, especially the 1st and 5th metatarsal bones, because these parts are usually the parts of the lower limbs where the force is more concentrated. If a person walks or plays sports for a long period of time, it is easy to cause mild damage to the bone at an early stage, which can lead to a slight fracture. If the person doesn’t take care of the rest at this time, the bone will gradually turn into a complete fracture and break, resulting in swelling and pain. If you rest in time after the appearance of minor symptoms, the symptoms will not progressively aggravate.
