Right subscapularis pain should be alert to muscle strain, localized lesions, subscapularis fasciitis, and lesions of organs around the scapula such as inflammation of the lungs, pleura, and tuberculosis. 1. Muscle strain: the right subscapularis muscle is under contraction and tension for a long time, resulting in muscle fatigue, which may form a local lesion of aseptic inflammation and stimulate the peripheral nerves, thus leading to the right subscapularis pain. 2. Local lesions below the right scapula: such as infection below the scapula, bone destruction of the scapula or tumor lesions in the surrounding area, which may cause pain below the right scapula due to inflammation, compression and other reasons. 3. Fasciitis below the right scapula: generally related to cold, excessive exercise, chronic strain and other factors, which can be relieved by resting and keeping warm. 4. Pleurisy around the right shoulder blade, pleural tuberculosis, pneumonia, tuberculosis may cause pain below the right shoulder blade due to inflammation, which may generally be accompanied by fever, fatigue, night sweating (abnormal sweating after going to sleep, and sweating stops after waking up) and other symptoms. If you experience pain below the right shoulder blade, you should seek medical attention.
