Numbness in the right hand is a relatively common clinical symptom, and the etiology is mainly nerve injury, such as peripheral neuritis and nerve trunk injury, etc. Patients can be treated with oral metocobalamin and vitamin B1, but more importantly, the etiology of numbness in the right hand should be clarified. If the peripheral neuritis is caused by diabetes, patients are advised to control sugar intake and take oral hypoglycemic drugs such as metformin, gliclazide, acarbose, etc. If the nerve damage is due to trauma, patients are advised to take, gangliosides and other nerve-nourishing drugs. If the nerve root injury is caused by cervical spondylosis, it is recommended that the patient pay attention to rest, improve cervical spine imaging, such as cervical spine CT, cervical spine MRI, and cooperate with physiotherapy, massage and other treatment methods if necessary. In summary, when hand numbness occurs, it is important to go to the hospital promptly to seek medical attention, to clarify the diagnosis as early as possible, and to treat the cause.
