USA Vein Clinics, Seattle

At USA Vein Clinics' locations across the country, cardiovascular doctors who specialize in circulation issues identify and treat vein problems. The symptoms they look for extend beyond varicose veins and spider veins to those with more serious implications, including swollen legs, say, or a feeling of heaviness in the lower body. 

Once they've reached a diagnosis, the physicians tackle the problem with an array of minimally invasive treatments. Sclerotherapy, for instance, works via injection, prompting visible veins to shut down, morph into harmless scar tissue, and slowly disappear. Folks can also opt for non-invasive, FDA-approved laser therapy, whose light targets and shrinks visible veins.
