Allergic reactions to the injection fluid may occur at the time of the procedure and are rarely serious. If you have a history of allergies, you have a greater chance of experiencing an allergic reaction to the agents. A minor allergic reaction will cause itching and swelling. To avoid any serious complications, your doctor will likely test the agents on a small area before applying the solutions to a larger area.
If you have any concerns or questions following this procedure, contact your doctor.
