Signs. The signs of venous incompetence: small blue or red snakelike veins close to the skin surface; ropy, slightly blue bulging varicose veins; prominent tortuous bluish veins beneath the skin called reticular veins; brownish skin discoloration about the ankle area; ulceration especially about the inside of the ankle. The symptoms have been nicely outlined by dr. King.
Not symptoms. It sounds as though you might have varicose veins but the symptoms you can get from varicose veins would be things like leg pain, aching, heaviness, tiredness, fatigue, itching, burning, swelling, throbbing, and the like. It sounds as though you might want to go see a vein specialist (phlebologist) and get things checked out.
Bulging Veins. Varicose veins are bulging grape-like appearing veins which are most commonly seen on the legs. These are due to leaking (refluxing) valves usually in the saphenous system. Some causes include hereditary, pregnancy, trauma and aging. Symptoms of VV include aching, cramping, itching, swelling, pain and heaviness in the legs. See a vein specialist for a full venous evaluation with an ultrasound.
Appearance. Dilated varicose veins may appear blue and bulging though the skin like "snakes". After veins are treated and there is no longer backward flow of blood in the legs, they will no longer look like this because the venous circulation will be treated and the blood will be redirected into the deep system, return normally back to the heart, and improve circulation.
