Sclerotherapy is a type of injection treatment for hemorrhoids, varicose veins (spider veins) and other vein issues. The injection therapy will help with aching, swelling, and burning. There are risks and side effects including bruising, red areas, skin sores, darkened skin, multiple red blood vessels, and more serious side effects. For example, inflammation and blood clots can form, which is part of what the treatment should be working against. Some have also had air bubbles form from the injection as well as allergic reactions.
The treatment will involve taking a needle and injecting a solution into the body. This solution is meant to flush out the vein getting the blood to flow better; therefore, reducing the hemorrhoid that formed. It has not been found very effective for the treatment of hemorrhoids, but some medical personnel still recommend it as a possible option. There are other treatments that are more effective and with fewer side effects.
