Shoulder arthroscopy is commonly performed using regional nerve blocks which numb your shoulder and arm. This local anaesthetic (numbing medicine) is injected in the base of your neck. This is where the nerves that control feeling in your shoulder and arm are located. In addition to its use as an anaesthetic during surgery, a nerve block will help control pain for a number of hours after the surgery is completed. The nerve block is combined with a light general anaesthetic, predominantly for your comfort.
Any surgical or invasive procedure carries risks. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner.
