Can varicose veins lead to serious complications?

This question asks for a sorting job. Which problems can varicose veins cause, and which of them need action? Here is what one published source says, and what we make of it.

Most people do not get serious complications

Serious complications are not the usual outcome. A few are named, though, so learn the four listed below and act on the signs. Do not wait on a sore or a painful lump.

The four problems Cleveland Clinic lists

On how common serious problems are, Cleveland Clinic says: "Most people don’t have serious complications from varicose veins."

On sores, it says: "Severe varicose veins can cause venous ulcers (sores)."

On clots, it names superficial thrombophlebitis and writes: "Blood clots can form inside varicose veins, causing this painful, but usually not dangerous, condition."

On progression, it says: "Varicose veins are sometimes an early sign of chronic venous insufficiency (CVI), which can get worse over time."

The source is these four passages. The reading that follows is ours. Sores, clots and a worsening vein condition are the items to watch for, and "usually not dangerous" is not the same as "ignore it."

Which of these applies to your legs

Ask the clinician treating you which of these four applies to your legs, if any. For background, a patient guide to varicose veins and a radiology overview of varicose vein evaluation and treatment give background in plain terms.

What the sources leave open

The passages say what can happen. They do not say how likely each problem is for you, or how soon one would appear. For a Westerville reader with visible veins, that gap is the reason to book an exam instead of guessing.
