Cervical spondylosis arm numbness is a common symptom of cervical spondylosis. If arm numbness occurs, the first thing to do is to go to a professional doctor at a specialized hospital, such as a spine surgeon, to take CT, MRI or X-rays to diagnose the type of cervical spondylosis. If it is a nerve root type of cervical spondylosis, early symptoms can be treated conservatively first. Conservative treatment is first cervical traction, which can open the intervertebral disc to eliminate the inflammation around the nerve root, which is beneficial to the patient. In addition, oral anti-inflammatory and analgesic drugs, cervical exercises, cervical and back exercises and nerve root blocks can also be used, and most of these treatments can provide relief. If relief is really impossible, surgical treatment can be performed for cervical discectomy, nerve root decompression, anterior internal fixation, etc. In addition, spinal cord cervical spondylosis can also produce hand numbness, which can be treated conservatively first by wearing a neck brace and braking, but not traction. If the effect of conservative treatment is poor, surgery will be considered. Surgical treatment generally involves anterior removal of the intervertebral disc in the cervical spine, spinal cord release via the anterior approach, and internal fixation in the anterior approach. If the segment is high or the pathology is more serious, and the posterior longitudinal ligament calcification involves multiple segments, posterior surgery, single-opening spinal canal enlargementplasty or other surgeries can be done. Therefore, in case of numbness of both upper limbs in cervical spondylosis patients, it is recommended to go to a specialized hospital for treatment.
