Frozen shoulder is a condition that leads to pain and stiffness of the shoulder. It’s also known as adhesive capsulitis or shoulder contracture.
The symptoms tend to gradually get worse over a number of months or years. You’ll typically experience shoulder pain for the first two to nine months, which can be severe, followed by increasing stiffness.
The stiffness may affect your ability to carry out everyday activities. In particularly severe cases, you may not be able to move your shoulder at all.
The condition may improve with time, but this can sometimes take several years.
