The early manifestations of varicose veins are firstly dominated by the tortuous expansion of the veins, or by the expansion of capillaries and reticular veins. The disease gradually develops and the varicose veins become more aggravated, mostly in the age of 50. Some patients only have the change of appearance without other discomfort, most patients can appear soreness, edema, pigmentation, night cramps and other discomforts, and the more serious ones can form long-term non-healing ulcers, commonly known as old rotten legs. 1, calf muscle (calf belly) sinking, soreness and weakness feeling: this is the first manifestation of most patients in addition to varicose veins, standing, walking and sitting for a long time is more obvious, more obvious in the afternoon than in the morning, and can be relieved after night rest. This is mainly due to the slow flow of blood in the varicose vessels, and the metabolites produced by the muscles cannot return in time and stagnate in the calf muscles. 2. Lower calf edema: It is manifested as sunken edema (a nest with one press), which is obvious in the afternoon or after prolonged standing or sitting, and relieved after night rest. Due to the destruction of the venous valves, varicose veins patients suffer from reverse blood flow after prolonged standing and sitting, resulting in higher venous pressure in the lower leg segment, vasodilatation and increased permeability, leading to extravasation of fluid from the blood vessels and the formation of edema. 3.Pigmentation: It shows that the local skin of varicose veins becomes brown, mainly due to the extravasation of some red blood cells in varicose veins and the release of iron ions due to disintegration and destruction. 4.Itching: It is obvious after sweating or when the skin is dry in winter. Due to edema pigmentation and other factors leading to local skin nutrient disorders, the circulation and metabolic function is blocked. 5, night cramps: mainly due to the calf muscles see poor venous reflux, acidic metabolites can not be discharged in a timely manner, part of the misdiagnosis of calcium deficiency, but the calcium supplementation is more than no significant effect. 6.Superficial vein thrombosis: It is a sudden redness and pain in the varicose vein, and the blood vessel becomes hard, sometimes it can spread along the varicose blood vessel, which is a more serious complication. Mainly due to the slow flow of blood in the varicose veins, if you sit or stand still for a long time, it is easy to form thrombus, which stimulates the vessel wall and leads to sterile inflammation. Strong stimulation of varicose vessels (acupuncture, gua sha, rubbing, etc.) leading to damage to the vessel wall can also lead to thrombosis. If the thrombus spreads to deep vein or dislodges, it will easily lead to pulmonary embolism. 7, thick and tough skin, ulcers, old rotten legs: increased vascular pressure leads to extravasation of intravascular material, long-term impact on the surrounding tissues, skin nutrient metabolism, resulting in the poor state of nutrition of the surrounding skin, the formation of thick and tough skin. If inadvertently damaged, it is not easy to heal, and even the ulcer surface gradually expanded, forming the old rotten leg.
