Shoulder pain

The ‘Rotator cuff’ muscles are the most common part of the shoulder to be injured, but there are other causes of shoulder pain too. These include: the Acromioclavicular joint – pain on the tip of the shoulder; Frozen shoulder or adhesive capsulitis – painful and gradual stiffening of the shoulder joint capsule; Referred shoulder pain (which actually comes from problems elsewhere, like the neck); and shoulder instability due to trauma.
