Frozen shoulder (adhesive capsulitis) can be very painful and often takes time to improve, even when diabetes is well controlled. If exercises and painkillers have not provided relief, further options include guided physiotherapy under supervision, capsular stretching, or hydrodilatation (distension injection) which helps loosen the stiff joint capsule without surgery.
