What are varicose veins?
Swollen, twisted veins that appear under the surface of the skin are called varicose veins.
They are a result of weak valves which cause pooling of blood and increased pressure in the veins. Varicose veins commonly occur in legs but can also develop in other parts of the body.
What are small varicose veins?
Small varicose veins or spider veins, as the name suggests, are damaged veins that are small in size (0.1 mm to 3 mm) and may appear on the surface of the legs or face. Small varicose veins are usually painless and harmless, but some people might need to treat them for cosmetic reasons.
Spider veins are often blue, purple, or red and develop in the form of thin lines, webs, or branches. They may be flat or slightly raised.
They may cause discomfort but are painless most of the time.
Long periods of sitting or standing can cause blood to pool within the leg veins, increasing the pressure within the veins. The increased pressure can cause the veins to stretch which results in weakening and damaging of the veins.
What are the symptoms?
Depending on their severity, varicose veins can cause various symptoms. These may include:
- Swelling of the legs or ankles
- An achy or heavy feeling within the legs
- Cosmetic concern
Varicose veins can also increase the risk of blood clots, thereby causing circulation problems in leg.
