If you can’t lift your arm because of pain, consider frozen shoulder, rotator cuff injury, shoulder fracture, and take medication, physical therapy, or surgery for the cause of the disease. 1. Frozen shoulder: Shoulder pain, limited active and passive activities of the shoulder joint, you can do shoulder exercises, oral non-steroidal anti-inflammatory drugs, such as diclofenac sodium enteric-coated tablets, hot compresses, waxing, ultrashort wave physiotherapy. 2. Rotator cuff injury: for minor injury, braking and recuperation for one month under the protection of shoulder support, oral Sanqi injury tablets or bone-setting capsules, and application of low-frequency pulsed electro-physiotherapy to promote healing. For serious tear, shoulder arthroscopy is needed. 3. Shoulder fracture: if there is fracture in the radiograph and the fracture is not displaced, take splint fixation; if the fracture is displaced or crushed, perform incision-replacement internal fixation surgery. The arm pain can not lift up to the hospital to identify the specific causes of the disease, for the cause of treatment. The use of drugs need to follow the doctor’s instructions.
