Introduction
In general, anesthesia is usually required before laser treatment for genital warts. Patients should inform the doctor of their allergy history prior to treatment, especially any allergies to anesthetic medications, to avoid allergic reactions. Mild redness and numbness at the treated site after anesthesia are typically normal and tend to subside gradually. After the procedure, it is important to keep the treated area clean and dry.
Generally, anesthesia is required before laser treatment for genital warts. The detailed explanation is as follows:
During treatment, the high temperature generated by the laser acts on both the wart tissue and surrounding skin or mucous membranes, which may cause significant pain. If the warts are located in sensitive areas rich in nerve endings—such as the perianal region, external genitalia, or cervix—the pain can be more intense. This may make it difficult for patients to cooperate during the procedure, thereby affecting treatment efficiency and outcomes. Anesthesia effectively reduces such discomfort and helps ensure the successful completion of treatment.
Prior to treatment, patients should inform their doctor of any personal history of allergies, especially to anesthetic agents, to avoid potential allergic reactions. Mild redness, swelling, or numbness at the treated site after anesthesia is usually normal and tends to resolve gradually. After the procedure, it is important to keep the treated area clean and dry, avoiding scratching or friction to prevent infection. Follow the doctor’s instructions for medication application and scheduled follow-up visits. Seek medical attention promptly if symptoms such as increased pain or fluid discharge occur.
