Lymph node dissection of lower limb edema can be gradually recovered in about 1-2 months, the specific recovery time needs to be analyzed according to the patient’s condition. Lymph node dissection mainly refers to the removal of diseased lymphatic tissues, which can effectively prevent the metastasis of malignant tumors. If the patient’s symptoms are more serious and the scope of lymph node dissection is wide, the edema of the lower limbs can be recovered in about 2 months; if the patient’s symptoms are relatively mild and the scope of lymph node dissection is small, the edema of the lower limbs can be recovered in about 1 month. Therefore, it is not possible to make a generalization, and it is necessary to analyze the specific situation. In addition, under the guidance of professional doctors, oral furosemide tablets, spironolactone tablets or hydrochlorothiazide tablets and other diuretic drugs can be used to promote the edema to subside, and daily life can also be used through the position of drainage, exercise, compression bandage, physiotherapy and other ways of adjuvant treatment, a two-pronged approach, which can play a very good effect. Patients are advised to go to the hospital for regular checkups, and if there is any abnormality, they should seek immediate medical attention.
