Right medial scapula pain may be related to fasciitis, rhomboid or trapezius muscle injury, scapula fracture and so on. 1. Fasciitis: the muscles and fascial tissues adjacent to the right medial scapula will cause local aseptic inflammatory reaction under the action of chronic injury and other factors, which will lead to the pain of the right medial scapula. Shoulder MRI can assist in the diagnosis. 2. Rhomboid muscle injury: rhomboid muscle can lead to muscle injury in different areas in case of trauma and long-term repeated cumulative injury, thus causing medial scapular pain. Local color ultrasound can assist the examination. 3. Trapezius injury: injury to the middle and lower bundle branches of the right trapezius muscle can cause right medial scapular pain in case of local inflammatory reaction and edema. Shoulder MRI can assist the diagnosis. 4. Scapular fracture: when the right scapula is fractured at the medial border, local pain can be caused by irritation of the fracture end or periosteal reaction. X-ray and CT examination of scapula can clarify the diagnosis. It is recommended to consult the doctor as soon as possible to clarify the condition and receive appropriate treatment for right medial scapula pain.
