Visible spider veins may just be the first sign of a deeper problem. Often spider veins can be a sign of venous insufficiency and reflux in the larger veins towards the surface of the skin known as superficial veins or perforators (veins that connect the superficial veins to the deep veins).
Varicose veins are often symptomatic and, when they are bulging, a rope like appearance can be noted.
Symptoms include: swelling, redness, aching, heaviness, inability to exercise, pain or tenderness along the vein, itching, burning, restless legs, changes in skin, and decreased sensation of touch.
If you have concerns it is always best to consult with your physician.
