Varicose veins don't develop overnight and can sometimes take many years to become a problem. In addition to their embarrassing, unsightly appearance, symptoms can include burning, aching, itching, pain, leg fatigue, heaviness, throbbing, ankle swelling, muscle cramping and tenderness to touch.  You may have symptoms even before varicose veins appear. Venous insufficiency may be present with symptoms as slight as ankle swelling in warm environments and with prolonged standing.

Sudden leg swelling that may or may not be accompanied by pain and redness could indicate a blood clot in the deep veins, and you should seek immediate medical attention.

Skin ulcers near your ankle may indicate a severe form of vascular disease that requires immediate attention.
