sclerotherapy is a medical procedure used to treat varicose veins and spider veins. It involves injecting a solution directly into the affected veins, causing them to collapse and eventually fade from view. This treatment is minimally invasive and can be performed in a doctor's office. The injected solution irritates the lining of the vein, leading to its closure. Over time, the body absorbs the treated vein, improving the appearance of the skin and alleviating symptoms like pain or swelling. Sclerotherapy is generally safe, with few side effects, and is often recommended for patients seeking relief from vein-related issues.
