Arm numbness caused by cervical spondylosis should firstly undergo relevant examination to clarify the degree of the disease. If the nerve compression is mild, it can be treated by medication, physical therapy, functional exercise, and so on. If the nerve compression is more serious, surgery is needed to relieve it. Cervical spondylosis, due to intervertebral stenosis or herniated discs, can compress the cervical nerves, resulting in numbness and tingling in the arms. You can first undergo a cervical CT or MRI examination to determine the degree of nerve compression. If the degree of compression is mild, it can be relieved by the following ways: 1. Oral medication: you can take non-steroidal anti-inflammatory drugs, such as: ibuprofen, diclofenac sodium, etc., to relieve the symptoms of numbness and tingling in the arm; you can also use local topical ointment containing the above medications for treatment. You can also take some nutritive nerve drugs, such as: methylcobalamin, vitamin B12, etc. for treatment. 2. Physiotherapy: massage, microwave, massage, acupuncture, moxibustion and other ways of treatment can be taken to promote local blood circulation, nutrition of local nerves, and alleviate the symptoms of discomfort. 3. Functional exercise: In the meantime of treatment, we should carry out functional exercises for the neck according to the physical condition, such as shoulder and neck exercises, small swallow flying, etc., to enhance the function of the cervical spine and alleviate the uncomfortable symptoms. If the degree of nerve compression in the neck is more serious, it is necessary to lift the nerve compression through surgical means to relieve the symptoms of hand numbness. The above drugs should be used under the guidance of clinicians to avoid adverse drug reactions.
