The shoulder is one of the most heavily used joints in the human body, allowing us to move our bodies around with great freedom. However, since shoulders are used every day, the joint tends to suffer a substantial amount of wear and tear, which can lead to pain or discomfort.
The joint is held together by a complex network of ligaments and tendons that link the muscles and bones together. Moreover, the shoulder joint is enclosed in a capsule of connective tissues. As time progresses, too much wear and tear cause the capsule to become thicker. As the tissue gradually thickens, it tightens the shoulder joint and causes a “frozen shoulder,” or pain and discomfort around that region.
For this reason, symptoms of adhesive capsulitis manifest themselves slowly and progressively worsen as time passes. Adhesive capsulitis typically develops gradually over one to three years, with the greatest symptom being a significant loss of range of motion.
