Local anaesthesia provides a numbing effect on the skin and can be administered as a cream but more commonly as an injection. The injection stops the local nerves from working and works fastest on pain nerve-fibres, which allows surgery to take place without any feeling or discomfort although you will still be able to feel pressure and movement.
The majority of minor ailments can be treated with surgery under local anaesthesia. Even some large problems can be treated by this method, depending on your preference. Occasionally, local anaesthesia can be combined with a mild sedative to calm nervous patients. Your options and preferences can be discussed with Chris during your consultation.
