Shoulder impingement refers to a painful limitation in shoulder movement due to either inflammation or injury of the shoulder rotator cuff tendons involved in shoulder movement, inflammation of a subacromial bursa (called bursitis) that separates the one of the tendons from the overlying bony arch and soft tissue structures, or a bony spur coming from the acromioclavicular joint(ACJ) joining the collar bone to the shoulder blade at the shoulder tip. These three conditions can easily be diagnosed clinically and using diagnostic ultrasound or MRI and treatment involves Physiotherapy and/or injections with steroid or PRP (see under).

Frozen shoulder, also known as adhesive capsulitis, is a painful stiffness with limited range of movement in your shoulder. It may happen after an injury such as falling onto the shoulder or overuse or from a disease such as diabetes or a stroke. Most of the time, this condition only improves with a special guided injection called high volume distention stretching the lining of the joint called the capsule followed by intensive Physiotherapy starting immediately after the injection. Untreated, this condition can last over two years.
