Adhesive capsulitis, often called frozen shoulder, causes painful stiffness and reduced range of motion in the shoulder.
Symptoms usually include shoulder pain, especially at night, and increasing stiffness that makes it hard to lift the arm, dress, or reach behind the back.
Imaging helps rule out another cause of shoulder pain and can support the diagnosis when the shoulder becomes stiff without a major injury.
X-rays may exclude arthritis, while ultrasound or MRI can help assess the joint capsule and rule out other shoulder problems.
Treatment often includes pain control, physiotherapy, stretching, injections, and patience because recovery can take time.
This entry explains the condition. The next step is having a radiologist interpret your specific scan, not a general definition.
