The symptoms of hand numbness and fever: 1, may be due to pressure on the tissues around the upper limbs, resulting in poor blood circulation and causing hand numbness and fever; 2, may be due to local nerve injury, such as cervical disc herniation or cervical spondylosis compression of the surrounding nerves and tissues, resulting in poor local blood circulation in the upper limbs, resulting in hand numbness and fever. If the symptoms of hand numbness and fever do not ease within a short period of time, you must go to a regular hospital in time to improve the MRI of the cervical spine, as well as the electromyography of both upper limbs and the arteriovenous ultrasound of both upper limbs, so that you can choose a reasonable treatment method after clarifying the cause, so that the symptoms of hand numbness and fever can be improved in a timely and effective manner.
