What is frozen shoulder?
Frozen shoulder (FS), also called adhesive capsulitis, is a condition where the connective tissues surrounding the shoulder joint become inflamed and scar tissue forms inside the capsule, causing extreme pain and stiffness. (Ease joint pain with these foods and supplements.)
It affects between three and five per cent of the population, most commonly women between the ages of 40 and 60, says Dr. Ryan Bicknell, a shoulder and elbow surgeon and an associate professor of orthopaedic surgery and mechanical and materials engineering at Queen’s University in Kingston, ON.
It’s also more common in people with diabetes and hypothyroidism, possibly because those conditions involve abnormalities of the endocrine system, which – among other duties, such as insulin production and hormonal balance – works to regulate inflammation in the body.
