Sclerotherapy involves injecting a hypertonic saline solution through a tiny needle directly into your spider veins, causing them to contract and collapse. This procedure is best suited for medium to large spider veins because it relies upon fitting a tiny needle into a tiny vein. The procedure is performed in the office by a UF Health physician assistant and is relatively painless.
