01
A valve problem, not only a visible vein
Varicose veins are widened, twisting veins just under the skin. They usually appear in the calf or thigh. The change starts when valves inside the vein no longer meet. Blood that should move up toward the heart slips back down while you stand.
The vein then stretches. Aching and heaviness tend to build through the day and ease if you lie down and raise the leg. That daily pattern is a useful clue.
02
Symptoms that are more than appearance
Some people are bothered mainly by how the veins look. Others develop itching, ankle swelling, brown staining of the skin, or a patch of hard skin above the ankle. An open sore in that area is a venous ulcer until proven otherwise.
- Bleeding from a surface vein needs firm pressure and a medical check
- A wound near the ankle should not be dressed for weeks without examining the veins
- Sudden swelling of one whole leg is not typical of ordinary varicose veins and needs urgent assessment for a clot

What an assessment adds
Looking at the leg is not enough to plan treatment. A duplex ultrasound shows which trunk vein is leaking and whether the deep veins are open. Stockings can ease symptoms. Procedures, when they are suitable, are aimed at the leaking vein mapped on that scan.
Veins can recur after treatment. A careful opinion explains that possibility instead of promising that the leg will be permanently free of veins.
This page is general education about vascular conditions and the way they are usually assessed. It does not diagnose a person or replace a consultation. Decisions about tests and treatment depend on an individual clinical assessment. Nothing on this website promises a particular result, a cure, or freedom from pain.
