Three months after the tibia fracture, walking will be swollen, considering the lower limb blood circulation is not good, the lower limb venous thrombosis, fracture has not healed, and so on. Three months after the tibia fracture, the local blood circulation of the fracture has not been fully restored, when walking on the ground, due to gravity, the blood in the lower limbs stagnation, the return blood flow is reduced, so it will cause swelling of the lower limbs. This condition usually takes 3~6 months to recover slowly, during this period, we should do more calf muscle exercise, such as doing ankle pump activities. There is also a situation because of the fracture due to prolonged braking caused by venous thrombosis of the lower limbs, will also appear when you get down to the ground when the calves are swollen, through the lower limb vascular ultrasound can be clearly diagnosed. If the fracture has not healed, it will be swollen and painful if you walk on the ground. Therefore, if the tibia fracture is swollen when walking for three months, you can elevate the lower limbs appropriately, and if it is accompanied by calf swelling and pain, you need to go to the hospital for checkup, to make sure that there is no venous thrombosis in the lower limbs, and to see how the fracture recovers.
