Shoulder muscle strains are usually caused by accidental strains while lifting or carrying heavy objects. If the local pain and swelling are obvious, and the movement is impaired, you should pay attention to the possibility of fracture or dislocation, and promptly improve the X-ray examination of the shoulder joint. If the local pain and swelling are not obvious and there is no obvious obstruction to movement, it is a simple muscle or soft tissue strain and can be treated with a local ointment such as flurbiprofen. After 24 hours of strain, you can choose to apply hot compresses, and at the same time use drugs to activate blood circulation and remove blood stasis, such as swelling and pain aerosols. In the case of obvious pain, you can apply Fotarine or take oral painkillers, such as Lupin Toine extended-release tablets, which can help relieve symptoms and recover in about 3 weeks.
