Sclerotherapy is a medical treatment used to eliminate varicose veins and spider veins. It consists of the injection of a sclerosing solution into the affected veins, which causes them to close and fade.

During sclerotherapy, a sclerosing solution is administered directly into the veins using a small needle. This solution irritates the walls of the veins, causing them to close and subsequently be reabsorbed by the body.

Sclerotherapy is generally not painful. Patients may experience a slight stinging or burning sensation during the injection of the sclerosing solution. However, local anesthesia or cooling techniques can be used to minimize any discomfort.

The number of sessions required may vary depending on the size and number of varicose or spider veins to be treated. On average, several sessions spaced over several months are recommended to obtain the best results.

Some common side effects of sclerotherapy include redness, bruising, burning sensation, or itching in the treated area. These side effects are usually mild and disappear in a short time.

The results of sclerotherapy are not immediate and may vary depending on each case. Generally, treated veins gradually fade over several weeks or months. Multiple sessions may be required to achieve the desired results.

After sclerotherapy, wearing compression stockings for a specific amount of time may be recommended to help improve results and reduce inflammation. Additionally, doctor's instructions should be followed, such as avoiding direct sun exposure and vigorous exercise for a certain period.

Sclerotherapy is a safe procedure when performed by trained medical professionals. However, as with any medical treatment, there are potential risks that should be discussed and evaluated during an initial consultation.
