The saying that “rotator cuff injury can be cured by itself” is unscientific and not true, and it can be cured by general treatment, medication and surgery under doctor’s guidance. 1. General treatment: pay attention to rest, avoid actions that can aggravate the injury; after ultrashort wave physical therapy can reduce swelling and pain in the shoulder joint. 2. Medication: For patients with rotator cuff injury with severe pain, pain relieving medication can be given under doctor’s instruction, such as ibuprofen, loxoprofen and so on. 3. Surgery: If the rotator cuff injury cannot be cured after conservative treatment, it is necessary to consider surgery, such as open surgery, arthroscopic surgery to restore the normal position of the rotator cuff and promote healing. It is recommended that rotator cuff injuries should be treated in time to find out the cause and standardize the treatment under the doctor’s guidance. The above medications should be used under the guidance of a doctor to avoid self-medication.
