The operation aims to increase the size of the subacromial area and reduce the pressure on the muscle. It involves cutting the ligament and shaving away the bone spur on the acromion bone. This allows the muscle to heal.
A nerve block is used during the operation which means that immediately after the operation the shoulder and arm may feel numb. This may last a few hours. After this the shoulder may well be sore and you will be given painkillers to help this whilst in hospital. These can be continued after you are discharged home. Ice packs may also help reduce pain. Wrap frozen peas or crushed ice in a damp, cold cloth and place on the shoulder for up to 15 minutes. In order to maintain a dry wound cover the dressing / wound with some cling film before applying the ice pack.
