The shoulder joint is the most mobile joint in the body. Its capsule (the tissue that surrounds the shoulder joint) has special properties that allows for this to happen. In a frozen shoulder (adhesive capsulitis), the capsule becomes tight, inflamed and scarred. This can result in severe pain and restriction of motion, which potentially can last two years.
The condition can be difficult to diagnose, especially in its early stages. Sometimes, the pain and stiffness is incorrectly attributed to a small partial tear of the rotator cuff. An accurate diagnosis early on can help with setting realistic expectations, avoiding unnecessary injections or surgery and hopefully speeding up recovery.
Any surgical or invasive procedure carries risks. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner.
