What is the cause of calf edema?

1, posture factors: long-term walking or standing, improper sitting posture, long-term sagging of legs, sedentary can lead to poor blood circulation of lower limbs, so reducing the assistance of muscle exercise to venous blood return will cause edema. Improper shoes can also cause edema. This edema will subside after rest. When the weather is hot, edema will get worse.

2. Climatic factors: When the weather is hot, most of the peripheral blood vessels of the human body are in an expanding state, which makes the capillaries congested, so the skin, subcutaneous tissue and soft tissue are slightly swollen, which is the reason why they swell with heat and contract with cold. I suggest you go to the hospital for a check-up, and then make specific symptomatic treatment according to the cause.
