The more common cause of numbness and sensation of heat in the hand is cervical spondylosis compressing the nerve root, or it may be peripheral nerve entrapment, such as elbow tunnel syndrome, carpal tunnel syndrome, etc. It is necessary to go to the orthopedic department in time to see a doctor for an interview and a preliminary analysis combined with physical examination. If the problem is cervical spondylosis, routine improvement of cervical MRI can determine the degree of nerve root compression and the specific segment. If it is peripheral nerve compression, electromyography can be improved. For cervical spondylosis, you can choose traction, or use methylcobalamin to nourish the nerve, and choose surgery if necessary in severe cases. If it is a peripheral nerve entrapment, a complete surgical release is required to help recovery.
