Many patients have the question, “I’ve had earthworm-like bruises popping out of my legs for years without any discomfort, is this a disease? Do I need treatment?” In fact, the so-called thick, bursting “veins” are varicose veins, and in the early stage, except for the appearance of the prominent veins, there are generally no symptoms. However, as the disease progresses (usually over several years to ten years), the damage gradually appears. The following are a series of consequences of the development of the disease: (a) swelling of the lower limbs, soreness after walking, patients often present swelling of the affected limbs in the evening after a day of activity, which can still be relieved after sleep. (ii) Skin pigmentation. Long-term venous hypertension leads to increased capillary permeability in the calf area, rupture of red blood cells after exudation, and deposition of ferritin under the skin, which makes the skin darken and develop from dots to flakes. (C) Local itching, ulceration and bleeding. The skin in the area of varicose veins itches due to the accumulation of metabolic products, and because the skin is undernourished and very fragile, once carelessness, such as bumping, scratching, or even mosquito bites can easily lead to rupture of varicose veins thus causing hemorrhage. Since bleeding is often not accompanied by other symptoms such as pain, patients often do not notice it, but if it happens at night while sleeping, it will lead to very serious consequences. The skin malnutrition can also lead to the occurrence of ulcers, which can be long-lasting, local malodorous pus, and even infection, which will not heal for a long time and become one of the manifestations of “old rotten leg”. (iv) Venous thrombosis. Some patients can form thrombosis in the superficial varicose vein, which is characterized by local redness, swelling and pain, hard lump formation, and pain affecting walking. If left untreated, the thrombus may spread upward or through the traffic vein to the deep vein, resulting in deep vein thrombosis, with the risk of life-threatening pulmonary embolism. In the past, due to economic constraints and concerns about surgery, many people would buy some false and exaggerated products in the market, which delayed the disease. Regular conservative treatment includes: (1) avoid prolonged standing or sitting, moving the lower limbs can use the pumping action of calf muscles to promote venous return; (2) elevating the lower limbs when lying down can relieve edema and other symptoms; (3) wearing elastic stockings with pressure gradient can slow down the development of the disease; (4) some drugs can play an auxiliary role in treatment, commonly used are Veritin, Mizarin tablets, etc. Conservative treatment can only relieve the symptoms of soreness and swelling, while surgery is the only way to cure the disease. At present, minimally invasive surgery is very mature, with fast recovery and less pain, and you can get out of bed and resume normal life on the same day after surgery. As for some small medical institutions borrow “no hospitalization, no surgery” to treat varicose veins, in fact, they use inexpensive sclerosing agent (sodium fish glycerate) injection, which has a high recurrence rate and complications, the majority of patients should remember to choose carefully.
