Superficial thrombophlebitis - The superficial varicose veins become red, hot, tender and painful and blood clots form in the superficial veins.  This can take many weeks to resolve. 

Chronic venous insufficiency - the development of brown discoloration of the skin at the ankle (pigmentation), thickening in the tissues around varicose veins (liposclerosis) are signs that more extensive tissue damage is occurring.

Varicose ulceration - if the tissue damage becomes great enough, venous ulcers can develop in the skin just above the ankle. .

Bleeding - It tends to be from smaller very superficial venous blebs in the skin.
