Possible causes of scapular suture pain include rib disease, myofascial injury around the scapula, lung disease, gallbladder disease and so on. 1. Ribbone disease: If there is tumor in the ribbone, or metastatic tumor caused by other parts of the body, it may cause local pain in the scapula on the same side of the diseased ribbone. 2. Myofascial injury around the scapula:Usually caused by sedentary lifestyle, long term work at desk, computer work and other people. This leads to muscle strain and myofasciitis in the scapula, which in turn leads to symptoms of pain at the scapula. 3. Lung diseases: probably when there are inflammatory foci, tumors or tuberculosis foci in the lungs, the nerves around the foci may be stimulated, and then corresponding scapular pain may appear. 4. Gallbladder diseases: In general, when there is an acute attack of cholecystitis, bile duct obstruction, gallbladder stones, etc., it usually leads to radiating pain in the scapular region. If you have scapular stitch pain, it is recommended to go to the regular hospital in time to find out the cause and treat it actively.
