How do i fix spider veins on my calves, thighs?

Ultrasound eval: You should first determine if these are associated with underlying varicose veins which may need to be treated prior to spider veins to decrease the chance of relapse. Ultrasound imaging may help in this regard.

Sclerotherapy!: After proper evaluation of the deep veins, examination for arterial or venous insufficiency, or history of phlebitis or deep venous thrombosis, sclerotherapy is still the gold standard for treatment of small spider veins. Laser treatments can often work as well, but can cause scarring more frequently and cost more than skillful vein injections with effective sclerosants! seek expert injectionist.

Sclerotherapy: I agree with drs. Placik and tholen, a proper evaluation first (including ultrasound) is always necessary. As long as there is no underlying trouble that is acting as a source for the spider veins on the legs, then they are best treated with sclerotherapy--sometimes in combination with laser for tiny veins, but sclerotherapy can treat veins of any size in the legs and laser is often not needed.

Vein evaluation.: If you have a few spider veins then sclerotherapy would be the treatment of choice. If you have many spider veins then you should consider having a venous evaluation with a venous reflux ultrasound to see if you have underlying reflux (leaking vein valves) which may be the cause of the spiders. A vein specialist would be able to evaluate you.
