I went out for fun a few days ago and walked too much. Now my feet and legs are swollen. Why?

Causes of lower limb edema include cardiogenic, renal, hepatic, malnutrition, and localized edema. This situation is not caused by kidney deficiency. It should be caused by lack of exercise, walking in a hurry for several days, and lack of endurance in both lower limbs, which causes edema. Oral diuretics can be used to reduce edema or local heat compresses. It is recommended to exercise moderately in daily life and do it step by step. Eat less salt and water in the near future. When lying down at night, raise your lower limbs above the heart. Helps reduce edema.
