The main symptom of rotator cuff injury is localized pain, which can be treated with medication such as ibuprofen extended-release capsules or surgery. 1. Symptoms: After rotator cuff injury, there will be pain, limitation of movement, swelling and other symptoms in the shoulder. After rotator cuff injury, it is impossible to use the injured shoulder automatically, and when the joint rotates internally or externally after the upper arm is straightened, the pressure and pain in the greater tuberosity and shoulder joint will be especially obvious. 2. Treatment: Rotator cuff injury can be treated with medication, taking anti-inflammatory drugs and painkillers such as ibuprofen extended-release capsules to relieve shoulder pain. If the rotator cuff injury is more serious, you can choose arthroscopic surgery, decompression of the corresponding parts, molding to reduce friction, and then hit the rivets to sew the torn ligament. It is suggested that rotator cuff injury should be diagnosed and treated as early as possible to avoid rotator cuff arthropathy or joint instability and other sequelae.
