Tingling in shoulder may be caused by cervical spondylosis, frozen shoulder, lung cancer and other diseases. 1. Cervical spondylosis: the cervical spine compresses and stimulates the nerve root, which leads to tingling pain in the shoulder in the innervated area, and even transmits to the upper limbs as well as the ends of the limbs, resulting in weakness as well as numbness. 2. Frozen shoulder: inflammation and pain around the shoulder joint caused by various reasons. Generally, the onset of frozen shoulder is relatively slow, and the tingling pain will appear unintentionally and gradually aggravate. 3. Lung cancer: after suffering from lung cancer, symptoms such as dyspnea and chest tightness will appear. However, if the lung cancer may metastasize or spread in middle or late stage, the lung cancer may affect the posterior pleura or the back spine, and then shoulder stabbing pain will appear. After the occurrence of shoulder tingling, patients should go to regular hospitals for examination in time, so as to clarify the cause of the disease and take targeted treatment.
