Numbness in the arm can be treated in the following ways: first, if the nerve compression caused by cervical spondylosis, cervical disc herniation, or cervical spinal stenosis causes numbness in the arm, the nerve compression can be lifted through cervical traction and surgical treatment to restore the nerve conduction function and reduce the symptoms of numbness in the arm; second, if the nerve compression causes numbness in the arm such as elbow canal syndrome, surgical treatment should also be used to completely lift the Secondly, if the nerve compression is caused by elbow canal syndrome, surgical treatment should also be used to completely release the nerve compression to relieve the clinical symptoms of arm numbness. In mild cases, we can temporarily consider conservative treatment, such as microwave therapy, ultrashort wave therapy, oral celecoxib, loxoprofen sodium, and micropol, to promote the recovery of nerve function. Patients with ineffective conservative treatment or recurrent symptoms still need surgical treatment to solve the problem, and postoperative exercises are needed to restore the normal function of the upper limbs in conjunction with muscle exercise.
