Adhesive capsulitis, also known as frozen shoulder, is a condition which freezes your shoulder to move within its range of motion. It is caused by the thickening and tightening of tissues in the shoulder joint, developing scar tissue over time, taking up the allotted space for the shoulder joint to rotate at its full capacity. People with weak immune systems, hormonal imbalance, and diabetes are prone to joint inflammations. In addition, stiff tissues, scar tissues, and adhesions that form over long periods (usually 3 - 9 months) of inactivity will restrain the shoulder’s range of motion. 

People who are sedentary are prone to getting frozen shoulders, especially those who came from an injury or other conditions that do not permit them to move or even do the normal physical activities. Some examples of these are people who are wearing a shoulder sling after an injury, people who suffered from stroke, or people who had surgery and need to remain as motionless as possible

Symptoms

Frozen shoulder symptoms are tricky. At first, certain shoulder movements will hurt, forcing you not to repeat such movements again. The next thing you know, reaching something in the cupboard and other normal everyday tasks are impossible.
