Varicose veins are a very common condition that causes excessive venous pressure due to the destruction of the venous valves over time. At the beginning of varicose veins in the lower extremities, there are often no obvious symptoms, but some people may feel itchy skin on the lower legs, swelling and soreness in the legs, a feeling of heaviness in the legs, and especially soreness in the lower legs and swelling in the ankles after standing all day. The more severe the degree of varicose veins, the more obvious the local pain in the lower extremities, and even the occurrence of blood stasis in the feet and the purple color of the ankles. In more severe cases, blood does not flow back easily and pigmentation, eczema-like dermatitis, and possibly bruised ulcers and sometimes bleeding from ruptured veins occur. In some cases, the vein wall becomes clotted and inflamed, known as thrombophlebitis, and the epidermis becomes red, swollen, painful, and even quite painful nodules may be palpable along the vein. If the clot moves with the blood flow to the lungs, a potentially fatal pulmonary embolism can occur.
