Frozen shoulder is also known as adhesive capsulitis. It is a medical condition characterized by pain and stiffness of the shoulder joint, as well as limitations of the range of motion.
Frozen shoulder is more common among people over the age of 40, which develops gradually. The tissue of the shoulder joint tends to become thicker and tighter, while the scar tissue develops over the time as well. This will eventually result in smaller motion range of the shoulder, swelling of the joint, pain and stiffness.
The signs and symptoms of frozen shoulder usually tend to develop over a long period of time, worsening as the time passes. First the movement of the shoulder starts to cause pain, while the range motion of the shoulder starts to become limited. As the time passes, the shoulder becomes stiffer and the range motion becomes even more limited. Moving the shoulder less and less will just make this condition worse because it increases its stiffness. Eventually, doing daily tasks becomes hard or even impossible, like reaching things from high shelves and even dressing.
