Veins are blood vessels that carry blood from your body's tissues to your heart. Veins have one-way valves that help keep blood flowing toward your heart. If your valves are weak or damaged, blood can back up and pool in your veins. This causes the veins to swell, which can lead to varicose or spider veins.
Sclerotherapy is a popular choice for spider and varicose vein issues since it costs less than surgery, requires no stressful or time-consuming hospital stay, has easy and unobtrusive post-treatment care, and enables an immediate return to work and daily activities in most cases.
