Because varicose veins are usually larger, knotted, and more twisted than spider veins, they require more medication for effective treatment. As a result, when you come in for treatment for varicose veins, a local anesthetic may be applied for your comfort.
During the procedure, you may experience some mild discomfort, cramping, or a short pinching sensation during the injection. However, these feelings usually subside after a few minutes.
In order to accurately target and close off the diseased veins, your doctor will use an ultrasound device to locate the center of the diseased vein. This process is repeated several times depending on the size and number of varicose veins that need to be treated.
After the treatment is complete, you will receive compression stockings to wear over the treated area for at least 48 hours. The compression stockings will help prevent bruising and will help the medication seal off the diseased veins.
Generally, you can expect larger varicose veins to disappear within a total of three or four months. However, you should see some improvement within a few weeks as the diseased vein walls begin to scar and break down. Compression stockings will also help reduce the risk of serious complications like blood clotting.
