Doctors aren’t quite sure why people develop frozen shoulder, although they’ve found it’s common after a surgery where you need to immobilize your arm or use a sling, or might occur after an injury, like to your rotator cuff. People who have diabetes are also more prone to frozen shoulder.
Luckily, if you do develop this painful condition, there are multiple treatments available to help you regain motion, ranging from physical therapy to medical treatments or surgery.
