At this time, it is necessary to carry out ultrasound of the arteries and veins of both lower limbs, and if there is an embolism, it is necessary to remove the embolism in time. Some people may also have hypoproteinemia, which may cause localized swelling, or swelling of both lower extremities, which can be relieved by medication. The swelling can be relieved by medication and other methods. In addition, local massage can be performed to relieve the swelling. After the surgery, you can disinfect the local area, usually try not to sit for a long time and stand for a long time, eat a light diet, remember spicy and fatty food, eat more calcium and vitamin-containing food to promote wound healing and bone growth.
