Symptoms of frozen shoulder mainly include shoulder joint pain, impaired mobility and muscle atrophy. 1. Shoulder pain: the pain in the early stage of frozen shoulder is usually more intense, swelling is more obvious, and the pain is mostly soreness and dull pain, which may spread to the same side of the neck or the whole upper limb. In the later stage of frozen shoulder, the pain will be gradually reduced, but the impaired mobility will be more obvious. 2. Mobility disorder: usually the longer the duration of the disease, the more obvious the mobility disorder, for example, combing hair, dressing, touching the opposite shoulder, lifting, abduction, extension and other movements will be limited or more difficult to do. 3. Muscle atrophy: For patients with a long history of the disease, due to pain or infrequent shoulder activities, the shoulder muscles will suffer from extensive atrophy, usually in the deltoid muscle area. In addition, patients with frozen shoulder usually have other symptoms such as cold shoulder and obvious pressure points around the shoulder, etc. It is recommended that patients go to the hospital in time and follow the doctor’s instructions to actively treat the disease, pay attention to keep the shoulder warm, correct the bad sitting posture, and do more shoulder exercise activities.
