Hemorrhoid surgery can be done under general anaesthesia or spinal anesthesia or caudal anaesthesia.
During general anesthesia the patient is usually unconscious and not aware of the surroundings.
During a spinal or caudal injection, an anesthetic, which numbs the back and buttock region, is injected into the spinal canal. The patient may be aware of what is happening and hear others talking as well, but he does not feel the pain.
