17th century shipping routes drastically improved once navigators began referring to actual maps of waterways instead of the veins on their thighs. Steer clear of veiny skin with today's Groupon to Lincoln Radiology Varicose Vein Clinic in Lincoln. Choose from the following options:

• For $75, you get a varicose-vein consultation (a $276 value) and diagnostic ultrasound (a $539 value; an $815 total value).
• For $99, you get a 30-minute spider-vein sclerotherapy treatment for the legs (a $280 value).
• For $160, you get both the varicose-vein consultation (a $276 value) with diagnostic ultrasound (a $539 value) and the 30-minute spider-vein sclerotherapy treatment for legs (a $280 value; a $1,095 total value).

Lincoln Radiology's elite team of vein-vanquishing physicians employs advanced technologies to hunt down and reform the cardiovascular slackers responsible for the legs' unsightly latticework. In the varicose-vein consultation, patients discuss their medical history and concerns with one of Lincoln Radiology's nurses, who then photographs affected veins on one or both legs. Cutting-edge ultrasounds are analyzed by the clinic's technologists, after which a physician interprets the images recorded by the ultrasound. If action is deemed necessary, patients can discuss potential treatment options, including laser treatment and sclerotherapy. The consultation and imaging take approximately one hour.

Lincoln Radiology recommends the same diagnostic ultrasound for the more cosmetically oriented spider vein treatment, but clients can also opt for the sclerotherapy alone. During a 30-minute sclerotherapy session, the clinic's vein-vetters inject tiny doses of a solution that causes useless avenues to shrivel and turn to scar tissue, which fades into obscurity and starts hanging out with slap bracelets.
