Spider veins are small, colored veins that can look like the legs of a spider.
If you see these symptoms, these are most likely spider veins or telangiectasias. Spider veins can occur singly or in large numbers (spider vein complexes). Spider veins are often considered to be unsightly and can cause leg pain and/or a feeling of heaviness. There is not always a correlation between amount of discomfort felt and the number of spider veins present; e.g. a person may have only a few spider veins and feel a fair amount of pain. Conversely, a person may have many spider veins and feel little or no pain.
