Early phenomena of lymphedema usually include limb edema, numbness in the affected area, disappearance of edema after elevating the limb, and skin lesions. 1. Limb edema: early lymphedema will lead to edema of the patient’s limbs. The most obvious is the edema of the lower limbs, which is below the knee and up to the ankle area, and also shows asymmetry. The edematous areas may also appear to be sunken when pressed. 2. Numbness of the affected area: due to the occurrence of edema in the limbs, it will lead to an increase in the weight borne by the patient’s body, and the pressure on the patient’s lower limbs will be aggravated, which will lead to numbness of the patient’s lower limbs. 3. Disappearance of edema after elevating the limbs: In the early stage of lymphedema, patients can make the swelling subside when they elevate the affected limbs. Without the effect of gravity, the fluid in the lower limbs will not accumulate in one place, and the edema will disappear. 4. Skin lesions: Early lymphedema will cause slight skin changes, the color of the skin will deepen, touching the affected skin will feel hard, and the epidermis will slowly become rough. Patients should consult a doctor in time when they find similar situations to avoid delays in their condition.
