Twenty-five million Americans, or roughly half of all men and women over age 50, have varicose veins.

These are veins that have become damaged and fail to regulate blood flow from the legs to the heart.

They are bulging, unsightly, and can lead to fatigue and pain.

Lately it's been Amelia the dog doing all the dancing at Dave Schwartzman's house. Dave says his left leg often feels tired and heavy.

The reason: varicose veins.

Dave decided to undergo a new procedure to treat the problem. It's all done under local anesthesia. Vascular surgeon Doctor Ken Adcock uses ultrasound to go inside the vein with a catheter, and then uses a radio frequency probe.

Radio frequency energy is used to heat the vein from inside, causing the vein wall to contract and close. This re-directs the blood to other healthy veins.

The treatment takes just a few minutes, and Adcock says it's also easier on the patient.

"It's a lot less traumatic to the surrounding tissues, a lot better as far as patient comfort," he explains.

Other varicose vein treatments, like laser or vein stripping, can leave bruises that can last for days. But with this procedure, Dr. Adcock says there's virtually no bruising or pain, and patients can return to regular activities in just 48 hours.

"I've been performing vascular surgeries for almost 25 years now, and this is a quantum leap forward," said the doctor.

"I was surprised at how quick it took -- and really pain free. And that's not an exaggeration. It was pain free," Dave reiterated.

Two hours after his procedure, Dave was up and around at home. He's not ready to dance with his little Amelia yet, but it won't be long. For now, she'll settle for a little peanut butter.

Doctors aren't sure what causes varicose veins. They do know the condition runs in families, and is more common in women than men.

Also, varicose veins seem to occur more often in people who spend many hours a day on their feet.
