An introduction to varicose vein symptoms
Varicose veins occur when veins become stretched, twisted, swollen or damaged. This leads to a disturbance in the normal flow of blood from the legs back to the heart.
Stretching of the vein causes damage to the small valves found inside veins – they start to ‘leak’, allowing blood to flow backwards towards the feet. Varicose veins can be found anywhere in the body but are most common in the legs. The rest of this page will refer only to varicose veins in the legs.
It has been estimated that over 30% of adults will develop varicose veins at some point in their lives. Many will not experience any symptoms. However, for others, symptoms of varicose veins may become problematic. Complications of varicose veins are rare but if these are present it is important to go to a doctor.

Symptoms of varicose veins include:
Often these symptoms are normal, but occasionally they can be an indication of a complication. Read our varicose veins complications page for more information.
