The first symptoms of varicose veins may appear long before the appearance of visible signs of the disease. They develop gradually, and are preceded by unfavorable factors - flat feet, excessive physical exertion, prolonged stay on the legs or compression of the veins with uncomfortable clothing. All this contributes to the stagnation of blood in the veins, a decrease in the elasticity of their walls and expansion.
Most often, varicose veins of the saphenous veins of the lower extremities develop. Its first symptoms can appear and disappear over many years and are manifested by heaviness and minor aching pains in the legs. But most often these signs are ignored, since they resemble the symptoms of ordinary fatigue or other diseases - flat feet, osteochondrosis and others.
With prolonged exposure to unfavorable factors, the further development of the disease occurs, and over time, aching pains become more pronounced. Due to venous stasis, heaviness in the legs appears. In the area of the ankle joint, edema forms in the evening - a sign of impaired venous outflow. And a venous pattern gradually begins to appear through the skin.
Further, in the absence of treatment and prevention, reduced vascular elasticity leads to a more noticeable expansion of the veins. They begin to show through the skin, mainly from the inside of the lower leg and thighs. In the places of their expansion, nodes that are hardly noticeable at the first stage are formed.
Violation of blood circulation and blood supply to tissues with varicose veins leads to darkening and pigmentation of the skin, its dryness and itching. Due to insufficient nutrition, it becomes thin, like parchment, and the slightest injury can lead to a long-lasting wound.
As the disease progresses, all signs of varicose veins worsen. There is a throbbing pain that is not associated with prolonged stay on the legs. The veins become pronounced and resemble convoluted cords that show through the skin.
The neglected forms of varicose veins can result in the formation of blood clots (due to stagnation of blood in the formed nodes of the veins) and trophic, non-healing ulcers (due to possible damage to the skin and its impaired blood supply).
