The doctor will have advised you to have the procedure in order to diagnose your skin condition. Once this is performed and the results are available, the doctor can advise the best treatment option. The doctor will need to know if you are allergic to any medications / anaesthetics. All procedures are done under local anaesthetic; which is a small injection around the area to be removed. This will sting and then become numb very quickly. You should not feel any pain during the procedure, but may experience some touch and pressure.
