Your anaesthetist will then inject a local anaesthetic to numb the area where the needle will be inserted. The will make inserting the needle feel less uncomfortable. Once certain the needle has been inserted in the right position they will inject anaesthetic through it.

Most surgical procedures carry some level of risk or possible complication. These will be discussed with you by your consultant or pre-assessment nurse prior to your procedure.
