When patients have rotator cuff injury, commonly used creams are generally divided into creams and patches. The main creams and patches used clinically are as follows: 1. Creams: commonly used creams include diclofenac sodium cream, ketoprofen gel, etc. These creams are absorbed through the skin after being applied to the shoulder and are more effective; 2. Patches: commonly used patches include wound and dampness pain relief cream, diclofenac sodium cream, flurbiprofen gel cream, etc. These These drugs are absorbed through the skin, and the degree of absorption is higher, not easy to make the skin allergic reactions. The topical creams are generally based on the therapeutic effects of activating blood circulation, removing blood stasis and relieving pain. After topical application, it can promote the absorption and decreasing of edema in the rotator cuff injury area to restore blood circulation in the rotator cuff, promote the repair of rotator cuff injury, and relieve the symptoms of pain in the rotator cuff. Ointment is only suitable for the early stage of rotator cuff injury or for relieving pain when the symptoms are mild. If the symptoms are more serious and the effect of using creams is poor, you should go to a regular hospital and ask your doctor to take surgical treatment, such as minimally invasive shoulder arthroscopy, according to your condition. After surgery, under the guidance of a clinician or rehabilitation doctor, shoulder rehabilitation can be carried out as soon as possible to reduce the sequelae.
