If you’re looking to remove spider veins or varicose veins, you may find that saline injections are infrequently used. Why? They’re unnecessary. Today, more effective solutions are available for treating damaged veins. In short, saline injections cause stinging upon injection. The saline solution mixes with the blood in larger veins, never making contact with the vein wall. As a result, saline injections are only effective for tiny spider veins. If sclerotherapy failed to remove your larger veins in the past, this is probably why. The good news? More effective and painless solutions are now available. Ask a board certified vein specialist (Phlebologist) which type of solution you should you use—and see if you’re ready to move beyond saline.
